Fix this by introducing `noexcept` like proposed in the warning.

Fix this by replacing the lambda with a simple ternary operator
expression.

Subject: [PATCH 10/63] Fix #12: Document reflection and introspection
 capabilities

Add comprehensive reflection documentation to cheatsheet.md covering type
inspection, object methods, Type_Info, function introspection, system
introspection, and Dynamic_Object reflection. Add missing global reflection
functions (type_name, is_type, function_exists, get_functions, get_objects,
type, dump_system, dump_object) and is_type_arithmetic to the Doxygen
prelude docs. Include a thorough test exercising all documented features.

+## Reflection and Introspection
+
+ChaiScript provides built-in reflection capabilities for inspecting types, functions, and objects at runtime.
+
+### Type Inspection
+
+```
+type_name(x)            // returns the type name of a value as a string
+is_type(x, "typename")  // returns true if x is of the named type
+type("typename")        // returns a Type_Info object for the named type
+
+// Examples
+type_name(1)            // "int"
+type_name("hello")      // "string"
+is_type(1, "int")       // true
+is_type(1, "string")    // false
+```
+
+### Object Inspection Methods
+
+Every object in ChaiScript supports these methods:
+
+```
+x.get_type_info()     // returns a Type_Info object for the value
+x.is_type("string")   // returns true if x is of the named type
+x.is_type(string_type) // returns true if x matches the Type_Info
+x.is_var_const()      // returns true if x is immutable
+x.is_var_null()       // returns true if x is a null pointer
+x.is_var_pointer()    // returns true if x is stored as a pointer
+x.is_var_reference()  // returns true if x is stored as a reference
+x.is_var_undef()      // returns true if x is undefined
+```
+
+### Type_Info
+
+`Type_Info` objects describe a type. You can get them via `type("typename")` or `x.get_type_info()`.
+
+```
+var ti = type("int")
+ti.name()              // ChaiScript registered name, e.g. "int"
+ti.cpp_name()          // mangled C++ type name
+ti.cpp_bare_name()     // C++ name without const/pointer/reference
+ti.bare_equal(other)   // true if types match ignoring const/ptr/ref
+ti.is_type_const()     // true if type is const
+ti.is_type_reference() // true if type is a reference
+ti.is_type_void()      // true if type is void
+ti.is_type_undef()     // true if type is undefined
+ti.is_type_pointer()   // true if type is a pointer
+ti.is_type_arithmetic() // true if type is arithmetic (int, double, etc.)
+```
+
+Built-in type constants are available: `int_type`, `double_type`, `string_type`, `bool_type`, `Object_type`, `Function_type`, `vector_type`, `map_type`.
+
+### Function Introspection
+
+Function objects support these introspection methods:
+
+```
+f.get_arity()                // number of parameters (-1 for variadic)
+f.get_param_types()          // Vector of Type_Info (first element is return type)
+f.get_contained_functions()  // Vector of overloaded functions (empty if not a conglomerate)
+f.has_guard()                // true if the function has a guard condition
+f.get_guard()                // returns the guard function (throws if none)
+f.get_annotation()           // returns the annotation description
+f.call([param1, param2])     // call the function with a vector of parameters
+
+// Examples
+def my_func(a, b) { return a + b; }
+my_func.get_arity()          // 2
+my_func.has_guard()          // false
+
+def guarded(x) : x > 0 { return x; }
+guarded.has_guard()          // true
+guarded.get_guard().get_arity() // 1
+
+// Calling functions dynamically
+`+`.call([1, 2])             // 3
+```
+
+### System Introspection
+
+```
+get_functions()        // returns a Map of all registered functions (name -> function)
+get_objects()          // returns a Map of all scripting objects (name -> value)
+function_exists("f")   // returns true if a function named "f" is registered
+call_exists(`f`, args) // returns true if f can be called with the given args
+dump_system()          // prints all registered functions to stdout
+dump_object(x)         // prints information about a value to stdout
+
+// Examples
+var funcs = get_functions()
+funcs["print"]                  // the print function object
+function_exists("print")        // true
+call_exists(`+`, 1, 2)          // true
+```
+
+### Dynamic_Object Reflection
+
+ChaiScript-defined classes are Dynamic_Objects internally. They support:
+
+```
+obj.get_type_name()    // returns the ChaiScript class name (e.g. "MyClass")
+obj.get_attrs()        // returns a Map of all attributes
+obj.has_attr("name")   // returns true if the attribute exists
+obj.get_attr("name")   // returns the value of the attribute
+obj.set_explicit(true) // disables dynamic attribute creation
+obj.is_explicit()      // returns true if explicit mode is enabled
+
+// Example
+class MyClass {
+  var x
+  def MyClass() { this.x = 10; }
+}
+var m = MyClass()
+m.get_type_name()      // "MyClass"
+m.get_attrs()          // map containing "x" -> 10
+type_name(m)           // "Dynamic_Object" (the underlying C++ type)
+m.is_type("MyClass")   // true (checks the ChaiScript class name)
+```
+

Subject: [PATCH 11/63] Fix #284: Add raw string support to avoid instring_eval

Add C++11-style raw string literals (R"delimiter(content)delimiter") to
ChaiScript. Raw strings do not process escape sequences or perform string
interpolation, solving the issue where base85 encoded data containing ${
sequences would trigger unwanted instring_eval. The implementation adds
Raw_String_() and Raw_String() parser functions and hooks them into the
expression parser.

Subject: [PATCH 12/63] Fix #591: Add comprehensive class definition docs to
 cheatsheet

The cheatsheet's "ChaiScript Defined Types" section was minimal, showing only
a basic class with one attribute and a getter. Expanded it to document block
syntax, open syntax, attribute keywords (var/attr/auto), constructor and method
guards, operator overloading, cloning, and added a test exercising all examples.

-## ChaiScript Defined Types
+## ChaiScript Defined Types (Classes)
 
-Define a type called "MyType" with one member value "a" and a getter
+ChaiScript supports user-defined types using the `class` keyword. Classes can have attributes,
+constructors, methods, guards, and operator overloads. There is no inheritance between
+ChaiScript-defined types, but C++ class hierarchies can be exposed (see *Class Hierarchies* above).
 
-### Preferred
+### Class Definition (Block Syntax)
+
+Define a type with attributes, a constructor, and methods inside a `class` block.
+The keywords `var`, `attr`, and `auto` are interchangeable for declaring attributes.
 
 ```
-class MyType {
-  var value;
-  def MyType() { this.value = "a"; }
-  def get_value() { "Value Is: " + this.value; }
-};
+class Rectangle {
+  var width
+  var height
+  def Rectangle(w, h) { this.width = w; this.height = h; }
+  def Rectangle() { this.width = 0; this.height = 0; }
+  def area() { this.width * this.height; }
+}
+
+var r = Rectangle(3, 4)
+print(r.area()) // prints 12
+```
+
+### Class Definition (Open Syntax)
+
+Equivalently, attributes and methods can be defined outside a block using the `TypeName::` prefix.
+
+```
+attr Circle::radius
+def Circle::Circle(r) { this.radius = r; }
+def Circle::circumference() { 2.0 * 3.14159 * this.radius; }
 ```
 
-### Alternative 
+Methods can also be added to an existing class after its initial definition:
 
 ```
-attr MyType::value;
-def MyType::MyType() { this.value = "a"; }
-def MyType::get_value() { "Value Is: " + this.value; }
+def Rectangle::perimeter() { 2 * (this.width + this.height); }
 ```
 
 ### Using
 
 ```
-var m = MyType(); // calls constructor
-print(m.get_value()); // prints "Value Is: a"
-print(get_value(m)); // prints "Value Is: a"
+var m = Rectangle(5, 10)
+print(m.area())       // prints 50 — method call syntax
+print(area(m))        // prints 50 — function call syntax (equivalent)
+```
+
+### Constructor and Method Guards
+
+Constructors and methods can have guard expressions (after `:`) that control which
+overload is selected at call time.
+
+```
+class Clamped {
+  var value
+  def Clamped(x) : x >= 0 { this.value = x; }
+  def Clamped(x) { this.value = 0; }  // fallback when guard fails
+}
+
+Clamped(5).value   // 5
+Clamped(-3).value  // 0
+
+class Abs {
+  var x
+  def Abs(v) { this.x = v; }
+  def get() : this.x >= 0 { this.x; }
+  def get() { -this.x; }
+}
+```
+
+### Operator Overloading
+
+Operators can be overloaded on user-defined types using backtick-quoted operator names.
+
+```
+class Vec2 {
+  var x
+  var y
+  def Vec2(x, y) { this.x = x; this.y = y; }
+  def `+`(other) { Vec2(this.x + other.x, this.y + other.y); }
+}
+
+var v = Vec2(1, 2) + Vec2(3, 4)  // v.x == 4, v.y == 6
+```
+
+Operators can also be overloaded as free functions with guards:
+
+```
+def `-`(a, b) : is_type(a, "Vec2") && is_type(b, "Vec2") {
+  Vec2(a.x - b.x, a.y - b.y)
+}
+```
+
+### Cloning Objects
+
+Use `clone()` to create a deep copy of a ChaiScript-defined object.
+
+```
+var original = Rectangle(10, 20)
+var copy = clone(original)
+copy.width = 99
+print(original.width)  // still 10
 ```

Add Function_Push_Pop to Switch_AST_Node case comparison to properly

Make Binary_Operator_AST_Node::do_oper static and public so it can be
reused by Switch_AST_Node for case equality checks, ensuring consistent
lifetime management across all operator invocations.

Subject: [PATCH 16/63] Fix #201: Suggestion: class Inheritance (#641)

* Fix #201: Add class inheritance support with Derived : Base syntax

Classes can now inherit methods and attributes from a base class using
C++-style syntax: `class Derived : Base { ... }`. Base class methods and
attributes are automatically available on derived objects. Derived classes
can override base methods by defining a method with the same name.
Inheritance relationships are tracked to support proper type matching
in the dispatch system.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* Address review: use implicit derived-to-base matching instead of copying base class functions

Instead of copying all base class methods/attributes into derived classes,
make the type matching system recognize inheritance relationships. Base class
methods now naturally match derived objects through dynamic_object_typename_match,
and dispatch ordering ensures derived overrides are preferred over base methods.

This is simpler (net -25 lines) and avoids duplicating function registrations.

Requested by @lefticus in PR #641 review.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* Add tests for passing derived objects to functions expecting Base

Tests cover: free functions calling base methods on derived objects,
polymorphic dispatch through containers, base attribute access on
derived objects, and multi-level inheritance (GrandChild : Derived : Base).

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* Add typed parameter tests for class inheritance

Use typed function signatures (e.g., `def call_do_something(Base obj)`)
instead of untyped parameters to test that derived objects are accepted
by functions expecting a base type, with correct polymorphic dispatch.

Requested by @lefticus in PR #641 review.

 parser

Convert \u escape sequences to proper UTF-8 characters instead of
passing through the literal \u notation. Supports the full BMP range
with correct 1, 2, 3, and 4-byte UTF-8 encoding.

Based on PR #483 by @olikraus, rebased onto current develop.

Subject: [PATCH 19/63] Fix #17: Add const variables in ChaiScript (#643)

* Fix #17: Add const local variable support to ChaiScript

Adds `const var`, `const auto`, and `const` as variable declaration
syntax that creates immutable local variables. A const_override flag
on Boxed_Value enables script-level constness without changing the
C++ type system integration. The parser, optimizer, and evaluator
are extended with Const_Var_Decl and Const_Assign_Decl AST nodes
that mirror their non-const counterparts but mark the value as const
after initialization.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* Address review: remove const_override, set const flag directly on Type_Info

Replace the m_const_override bool on Boxed_Value::Data with a
Type_Info::make_const() method that sets the const bit in m_flags
directly. This ensures constness is visible everywhere consistently,
including places that check get_type_info().is_const() directly.

Requested by @lefticus in PR #643 review.

Subject: [PATCH 20/63] Fix #256: ChaiScript::get_locals() does not show
 functions (#640)

* Fix #256: Expose get_function_objects() and get_scripting_objects() in public API

The ChaiScript_Basic public API only exposed get_locals() for inspecting
runtime state from C++, requiring users to work around this via
chai.eval("get_functions()") to access function objects. Added
get_function_objects() and get_scripting_objects() as public methods on
ChaiScript_Basic, delegating to the existing Dispatch_Engine methods,
matching the pattern already used by get_locals().

* Address review: add tests for get_scripting_objects()

Subject: [PATCH 21/63] Fix #592: Local variable saw_eol in Class_Statements()
 was always true (#646)

The saw_eol variable in Class_Statements() was initialized to true and
only ever set back to true, making the "missing line separator" check
unreachable. The fix separates Def (block statement ending with }) from
Var_Decl (simple statement) so that Var_Decl sets saw_eol to false,
matching the pattern used in Statements() for simple expressions.

Subject: [PATCH 22/63] Fix #554: Document the difference between add,
 add_global, and set_global (#649)

Updated the cheatsheet to clearly explain that `add` creates thread-local
scoped variables while `add_global`, `add_global_const`, and `set_global`
create global variables shared between all threads. Added a summary table
comparing scope, thread safety, and conflict behavior. Also added a test
exercising the key behavioral differences between these methods.

+
+Global variables are shared between all threads and are visible from any scope (including inside
+functions). Use these when you need a variable accessible everywhere.
+
+```cpp
+chai.add_global_const(chaiscript::const_var(somevar), "somevar"); // global const, throws if value is non-const or object already exists

* Fix #615: Switch from Travis CI to GitHub Actions

Add a GitHub Actions CI workflow with a full build matrix covering
linux, macOS, and Windows with both GCC and Clang compilers, Debug
and Release build types, and optional ASan+UBSan sanitizers (24 builds
total). Windows builds use MSYS2 for GCC/Clang toolchains. The workflow
relies on CMake and CTest to drive configuration, building, and testing.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* Address review: use native compilers, remove MSYS/MinGW

Use Visual Studio (MSVC) on Windows, Apple Clang on macOS, and GCC on
Linux. Remove MSYS2/MinGW toolchain setup entirely. Split into three
separate jobs for clarity. Fix workflow validation issues.

Requested by @lefticus in PR #658 review.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* Address review: add workflow_dispatch to enable manual CI runs on fork

Add workflow_dispatch trigger so the workflow can be manually run on the
leftibot fork to verify that GitHub Actions are working correctly.

Subject: [PATCH 24/63] Fix #607: Remove unnecessary forward declarations that
 cause C++20 build failures (#647)

The forward declarations of AST_Node_Trace and eval_error at the top of
chaiscript_common.hpp introduced these types as incomplete before the standard
library headers were fully processed. On clang/libc++ in C++20 mode, this
caused compilation errors because std::vector<AST_Node_Trace> was instantiated
while the type was still incomplete. Since the full definitions of both types
appear later in the same file (and nothing between the forward declarations
and the definitions references them), these forward declarations are unnecessary
and removing them prevents the incomplete type issue.

Subject: [PATCH 25/63] Fix #660: Windows builds are broken (#661)

* Fix #660: Fix Windows builds, remove Appveyor, add sanitizer CI builds

Add missing #include <chrono> to src/main.cpp which caused MSVC build
failures since high_resolution_clock and duration_cast were used without
the header (GCC/Clang included it transitively). Remove obsolete
appveyor.yml (superseded by GitHub Actions). Add ASAN+UBSAN build
jobs for Linux and macOS in the CI workflow.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* Address review: add Windows ASAN+UBSAN sanitizer support

- Add MSVC-native ASAN support in CMakeLists.txt (/fsanitize=address)
  with /RTC removal and /INCREMENTAL:NO (both incompatible with ASAN)
- Add Windows MSVC ASAN CI job
- Add Windows ClangCL ASAN+UBSAN CI job (UBSAN requires Clang, not
  available in native MSVC)
- Fix sanitizer guard to include AppleClang (macOS sanitizer jobs were
  silently not enabling sanitizers)

Requested by @lefticus in PR #661 review.

* Address review: remove Windows sanitizers, add TSAN for Linux/macOS

Remove windows-sanitizers and windows-clangcl-sanitizers CI jobs.
Add linux-tsan and macos-tsan CI jobs using ENABLE_THREAD_SANITIZER.

Subject: [PATCH 26/63] Fix #405: push_back() on script-created vector has no
 effect if vector_conversion is in effect (#663)

* Fix #405: push_back() on script-created vector has no effect with vector_conversion

When both vector_type<T> and vector_conversion<T> are registered, the
dispatch scoring treats all parameter mismatches equally. This causes
the C++ push_back (for the converted type) to be selected over the
built-in one when both have the same number of type differences. The
converted function operates on a temporary copy of the vector, silently
discarding the mutation. The fix deprioritizes overloads that require
type conversion on the first parameter (the object/receiver), ensuring
functions matching the receiver type exactly are always tried first.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* Address review: remove issue references from comments, add round-trip conversion tests

Requested by @lefticus in PR #663 review.

Subject: [PATCH 27/63] Fix #472: Emscripten Frontend (#662)

* Fix #472: Add Emscripten/WebAssembly build for browser-based ChaiScript

Port Rob Loach's ChaiScript.js work (https://github.com/RobLoach/ChaiScript.js)
into the main repository as an Emscripten build target. Adds a GitHub Actions
workflow that builds ChaiScript to WebAssembly and publishes artifacts (JS, WASM,
HTML) for embedding in the official ChaiScript.com website. Includes an HTML
interactive playground frontend and a native test validating the eval API surface.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* Address review: publish WASM assets as release under wasm-latest tag

Add a publish job to the emscripten workflow that creates a prerelease
tagged wasm-latest with chaiscript.js, chaiscript.wasm, and
chaiscript.html as downloadable assets. Runs only on pushes to the
develop branch. The website repo can fetch these via the public
GitHub Releases API on a daily cron without any cross-repo auth.

Subject: [PATCH 28/63] Fix #459: Fill out the set of conversion functions for
 all POD types (#664)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Previously, to_<type> only accepted a string or the same type (identity),
and <type>() constructors only accepted Boxed_Number. This left gaps such as
to_int(char), to_char(int), char(string), int(string), and to_double(char).

Add two overloads to bootstrap_pod_type: to_<name>(Boxed_Number) enables
cross-type numeric conversions (e.g. to_int('A') → 65, to_char(65) → 'A'),
and <name>(string) via parse_string enables construction from strings
(e.g. char("A") → 'A', int("65") → 65, double("3.5") → 3.5).

Subject: [PATCH 29/63] Fix #655: Async issues with threads outliving the
 chaiscript engine (#656)

* Fix #655: Join async threads before engine destruction to prevent heap-use-after-free

Issues #632 and #636 (PRs #651 and #653) both stem from the same root cause: async
threads spawned via async() can outlive the Dispatch_Engine, accessing shared state
(global objects map, type maps) after it has been destroyed. The fix moves async()
registration from the stdlib module into ChaiScript_Basic, where spawned threads are
tracked via Dispatch_Engine. The engine's destructor now joins all outstanding async
threads before destroying shared data structures.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* Address review: follow rule of 5, explicitly default move operations

Requested by @lefticus in PR #656 review.

Subject: [PATCH 30/63] Fix #625: function_less_than comparator violates
 strict-weak ordering (#654)

The function_less_than comparator used by std::stable_sort violated the
strict-weak ordering requirement in two ways: (1) functions with different
arities but matching overlapping parameters were treated as equivalent,
breaking transitivity, and (2) the dynamic_object_type_name comparison
silently fell through when one side had an empty type name. Fixed by
ordering by arity when overlapping parameters match, and imposing a total
order on dynamic object type names.

Subject: [PATCH 31/63] Fix #524: Support std::vector of non-copyable types
 like std::unique_ptr (#648)

Several STL bootstrap functions unconditionally instantiated copy-dependent
operations (copy constructor, assignment, push_back/push_front by const ref,
insert_at, and resize with fill value), causing compilation failures when
registering containers of move-only types like std::unique_ptr. Guard these
operations with if constexpr(std::is_copy_constructible_v<value_type>) so they
are only compiled when the element type supports copying.

Subject: [PATCH 32/63] Fix #146: Add configuration to bypass the registering
 of 'built-in' functions. (#642)

* Fix #146: Add configuration options to selectively disable built-in functions

Add new Options enum values (No_Stdlib, No_IO, No_Prelude, No_JSON) that
allow users to control which parts of the standard library are registered.
Std_Lib::library() now accepts an options vector, and the ChaiScript
convenience class forwards its options to the library builder. This enables
use cases where only custom functions should be exposed to script users.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* Address review: split Options into Options and Library_Options enums

Separate system-level options (No_Load_Modules, Load_Modules, No_External_Scripts,
External_Scripts) from library-level options (No_Stdlib, No_IO, No_Prelude, No_JSON)
into two distinct enum types. Add Library_Options as a parameter to the ChaiScript
constructor. Update tests to demonstrate both ChaiScript_Basic (explicit Std_Lib::library
call) and ChaiScript (library options via constructor parameter) usage.

* Add cheatsheet documentation for Options and Library_Options

Documents the two-enum configuration system: Options (engine-level:
load_module, use, eval_file) and Library_Options (stdlib-level:
No_Stdlib, No_IO, No_Prelude, No_JSON), with usage examples for
both ChaiScript and ChaiScript_Basic constructors.

 Note that ChaiScript cannot be used as a global / static object unless it is being compiled with `CHAISCRIPT_NO_THREADS`.
 
+## Engine Options (`Options`)
+
+Engine-level options control which scripting capabilities are exposed. These are passed as a `std::vector<Options>` to the `ChaiScript` or `ChaiScript_Basic` constructor.
+
+| Option | Effect |
+|--------|--------|
+| `Options::Load_Modules` | Enables `load_module()` in scripts (default) |
+| `Options::No_Load_Modules` | Disables `load_module()` |
+| `Options::External_Scripts` | Enables `use()` and `eval_file()` in scripts (default) |
+| `Options::No_External_Scripts` | Disables `use()` and `eval_file()` |
+
+```cpp
+// Sandboxed engine: no dynamic module loading, no external script evaluation
+chaiscript::ChaiScript chai({}, {},
+    {chaiscript::Options::No_Load_Modules, chaiscript::Options::No_External_Scripts});
+```
+
+## Library Options (`Library_Options`)
+
+Library-level options control which parts of the standard library are registered. These are passed as a `std::vector<Library_Options>`.
+
+| Option | Effect |
+|--------|--------|
+| `Library_Options::No_Stdlib` | Disables the entire standard library (types, I/O, prelude, JSON — everything) |
+| `Library_Options::No_IO` | Disables `print_string` and `println_string` (and the prelude's `print`/`puts` wrappers) |
+| `Library_Options::No_Prelude` | Disables the ChaiScript prelude (`print`, `puts`, `filter`, `map`, `foldl`, `join`, etc.) |
+| `Library_Options::No_JSON` | Disables `from_json` and `to_json` |
+
+With the `ChaiScript` convenience class, pass library options as the fourth constructor parameter:
+
+```cpp
+// No I/O functions
+chaiscript::ChaiScript chai({}, {}, chaiscript::default_options(),
+    {chaiscript::Library_Options::No_IO});
+
+// No JSON support
+chaiscript::ChaiScript chai({}, {}, chaiscript::default_options(),
+    {chaiscript::Library_Options::No_JSON});
+
+// Completely bare engine — no stdlib at all
+chaiscript::ChaiScript chai({}, {}, chaiscript::default_options(),
+    {chaiscript::Library_Options::No_Stdlib});
+
+// Combine both: no external scripts and no I/O
+chaiscript::ChaiScript chai({}, {},
+    {chaiscript::Options::No_Load_Modules, chaiscript::Options::No_External_Scripts},
+    {chaiscript::Library_Options::No_IO});
+```
+
+With `ChaiScript_Basic`, pass library options directly to `Std_Lib::library()`:
+
+```cpp
+chaiscript::ChaiScript_Basic chai(
+    chaiscript::Std_Lib::library({chaiscript::Library_Options::No_IO}),
+    create_chaiscript_parser(),
+    {}, {},
+    {chaiscript::Options::No_Load_Modules, chaiscript::Options::No_External_Scripts});
+```
+
+Note: `No_Prelude` disables the prelude script which defines convenience functions like `print` (which wraps `print_string`). If you disable the prelude but not I/O, `print_string` and `println_string` are still available.

Subject: [PATCH 33/63] Fix #473: Allow assignment expressions in return
 statements (#665)

The Return() parser function called Operator() to parse the return value,
which only handles arithmetic/logical operators but not assignments. Changed
it to call Equation(), which wraps Operator() and adds assignment parsing.
This is consistent with how If, For, and function argument parsing already
work. Enables `return foo = 5`, `return x += 1`, etc.

Subject: [PATCH 34/63] Fix #470: Expose find() for associative container types
 (#668)

Add a native find() method to unique associative containers (e.g., Map)
that returns the mapped value if the key exists, or an undefined
Boxed_Value if not. This allows checking for key existence without
mutating the container (unlike operator[]) or requiring exception
handling (unlike at()).

Subject: [PATCH 35/63] Fix #571: How to redirect "cout" and "print" to a
 microsoft Windows 10 window?  (#657)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* Fix #571: Add per-instance IO redirection via set_print_handler/set_println_handler

The print_string and println_string functions were previously registered as static
functions writing directly to stdout, making it impossible to redirect ChaiScript
output to custom destinations (e.g., GUI windows, loggers, or buffers). This moves
their registration from Bootstrap::bootstrap() to ChaiScript_Basic::build_eval_system()
as lambdas that dispatch through configurable std::function handlers, allowing each
ChaiScript instance to independently redirect its output via set_print_handler() and
set_println_handler().

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* Address review: add IO redirection section to cheatsheet

Documents set_print_handler() and set_println_handler() with usage
examples for GUI embedding and output capture.

Requested by @lefticus in PR #657 review.

* Address review: define println in terms of print, expose set_print_handler to ChaiScript

Remove separate println_handler — println_string now dispatches through the
single print handler with a newline appended. Only set_print_handler is
needed to redirect all output. The set_print_handler function is also
registered in the ChaiScript engine, so scripts can capture and redirect
their own output.

Requested by @lefticus in PR #657 review.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* Address review: populate null print handler when No_IO is set

When No_IO is active, the default m_print_handler is now a no-op instead
of writing to stdout. The stdout handler is only installed when No_IO is
not set. Users can still override the handler via set_print_handler()
even with No_IO enabled.

+## IO Redirection
+
+By default, ChaiScript's `print()` and `puts()` functions write to stdout. You can redirect
+output on a per-instance basis by setting a single print handler. Both `println_string`
+(used by `print()`) and `print_string` (used by `puts()`) dispatch through the same handler —
+`println_string` simply appends a newline before calling it.
+
+```cpp
+chaiscript::ChaiScript chai;
+
+// Redirect all output (print_string and println_string both use this handler)
+chai.set_print_handler([](const std::string &s) {
+  my_log_window.append(s);
+});
+```
+
+This is useful for embedding ChaiScript in GUI applications, logging frameworks, or any
+context where stdout is not the desired output destination.
+
+```cpp
+// Example: capture all output to a string
+std::string captured;
+chai.set_print_handler([&captured](const std::string &s) {
+  captured += s;
+});
+
+chai.eval("print(42)");    // captured == "42\n"
+chai.eval("puts(\"hi\")"); // captured == "42\nhi"
+```
+
+The print handler can also be set from within ChaiScript itself via `set_print_handler`:
+
+```chaiscript
+// Redirect output from within a script
+set_print_handler(fun(s) { my_custom_log(s) })
+```
+
 ## Extras
 ChaiScript itself does not provide a link to the math functions defined in `<cmath>`. You can either add them yourself, or use the [ChaiScript_Extras](https://github.com/ChaiScript/ChaiScript_Extras) helper library. (Which also provides some additional string functions.)

Subject: [PATCH 36/63] Fix #398: Allow overriding [] operator with string
 index on Dynamic_Object subtypes (#667)

The built-in Dynamic_Object::get_attr was always winning dispatch over
user-defined [] overrides when a string index was used, because its C++
type signature (Dynamic_Object, const string&) scored numdiffs=0 while
ChaiScript-defined functions had higher numdiffs due to undefined type
info. The fix deprioritizes generic C++ Dynamic_Object functions when the
actual first argument is a specific subtype, and maps named ChaiScript
type parameters to Dynamic_Object type_info for correct dispatch scoring.

Subject: [PATCH 37/63] Fix #666: TSAN builds don't actually use threads (#670)

* Fix #666: TSAN builds don't actually use threads

TSAN builds did not explicitly enable MULTITHREAD_SUPPORT_ENABLED, so they
relied on the CMake default. This adds -DMULTITHREAD_SUPPORT_ENABLED=ON to
both TSAN jobs and expands the CI matrix to cover threading on/off with
Debug/Release for Linux, macOS, and Windows MSVC. Also excludes async-dependent
.chai tests from non-threaded builds and adds a Threading_Config_Test to verify
the threading configuration is correct in both modes.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* Address review: use Ninja generator for all unix CI targets

Requested by @lefticus in PR #670 review.

Subject: [PATCH 38/63] Fix #634: Add divide-by-zero check for modulo
 assignment operator (#672)

The assign_remainder (%=) case in Boxed_Number::go was missing the
check_divide_by_zero guard, causing a hardware SIGFPE on integer
modulo by zero. Also moved a misplaced check_divide_by_zero from
assign_bitwise_and (&=) where it was erroneous. Additionally, the
catch block in Equation_AST_Node::eval_internal was masking the
arithmetic_error exception as a generic "unsupported operation" error;
arithmetic_error is now re-thrown to provide the correct error message.

Subject: [PATCH 39/63] Fix #594: Map keys become dangling references when
 pushed into Vector (#650)

The Handle_Return_Ref specialization for const references was wrapping
return values in std::cref() while marking them as return values
(is_return_value=true). This caused Vector.push_back() to store the
reference directly without cloning, since it assumes return values are
freshly created temporaries. When the source object (e.g., a map) went
out of scope, the vector contained dangling references to freed memory.

The fix sets is_return_value=false for const reference returns, which
correctly triggers push_back to clone the value instead of storing a
bare reference. This is consistent with the non-const reference handler
(Handle_Return<Ret &>) which also does not set the return value flag.

* Fix #635: Segfault in async result via dangling pointer from optimized for loop


* The optimized for loop (chaiscript_optimizer.hpp) stored the loop

Subject: [PATCH 41/63] Fix #499: Add object_from_json, map_to_object, and
 object_to_map functions (#676)

Add object_from_json as a non-breaking alternative to from_json that returns
a Dynamic_Object instead of a Map, enabling dot-access syntax on JSON fields
(e.g. obj.name instead of obj["name"]). Nested JSON objects become nested
Dynamic_Objects. Also add map_to_object and object_to_map for Python-style
interconversion between maps and objects.

Subject: [PATCH 42/63] Fix #61: Comprehensive exception test suite and fix for
 silently swallowed exceptions (#681)

When all typed catch blocks failed to match a thrown exception's type,
handle_exception() would silently discard the exception and return a
default-constructed Boxed_Value instead of propagating it. This meant
code like `try { throw(42) } catch(string e) { }` would swallow the
int exception rather than letting it propagate to an outer handler.

The fix adds an explicit re-throw when no catch block matches, and
restructures eval_internal() with a nested try/catch to ensure the
finally block still executes before the unhandled exception propagates.

Subject: [PATCH 43/63] Fix #601: Allow operator functions to accept any type
 with an add() method (#686)

The operator functions in chaiscript::bootstrap::operators (equal, not_equal,
assign, etc.) hardcoded Module& as their first parameter, preventing
chaiscript::utility::add_class for enum types from working when passed a
ChaiScript& reference directly. Added a second template parameter ModuleType
to all operator functions so they accept any type that provides an add()
method, matching the already-templatized add_class functions in utility.hpp.

Subject: [PATCH 44/63] Fix #678: Add WASM exception support to Emscripten
 build (#689)

ChaiScript relies heavily on C++ exceptions for error propagation, but
the Emscripten build was missing the -fwasm-exceptions flag. Without it,
any C++ exception in the WASM module causes an abort instead of being
catchable by JavaScript. Added -fwasm-exceptions as both a compile and
link option, and added a regression test verifying exception propagation
through the eval wrapper functions.

Subject: [PATCH 45/63] Fix #628: Grammar railroad diagram (#673)

* Fix #628: Add EBNF grammar for railroad diagram generation

Add a formal EBNF grammar file (grammar/chaiscript.ebnf) that can be
pasted into rr (https://www.bottlecaps.de/rr/ui) to produce navigable
railroad diagrams of ChaiScript's syntax. The grammar was validated
against the parser implementation and covers all language constructs
including class inheritance, guard conditions, raw strings, and const
declarations that were missing from the original proposal. A reference
section was added to the cheatsheet, and a regression test exercises
every documented grammar construct.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* Address review: add grammar railroad diagram link to README

Add a Grammar section to readme.md linking to the EBNF grammar file
and to mingodad's railroad diagram generator for direct viewing.

Requested by @lefticus in PR #673 review.

Subject: [PATCH 46/63] Fix #552: Feature-request: nested namespaces (#675)

* Fix #552: Support nested namespaces via dotted names

Namespaces can now be nested using dotted name syntax, both from C++
(register_namespace(gen, "constants.si")) and from script
(namespace("constants.si")). Parent namespaces are auto-registered when
absent, and child namespaces are automatically nested into their parent
on import. This allows clean hierarchical organization like
constants.si.mu_B instead of flat names like constants_si.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* Address review: use :: instead of . as nested namespace separator

Switch from dotted names (e.g. "constants.si") to C++-style ::
separator (e.g. "constants::si") for nested namespace declarations,
both in the C++ API (register_namespace) and in script (namespace()).

The original implementation used . because namespace members are
accessed via dot notation at runtime (constants.si.mu_B), making the
declaration separator match the access syntax. However, :: is more
consistent with C++ namespace conventions and aligns with ChaiScript's
existing use of :: for method (def Class::method) and attribute
(attr Class::attr) declarations.

Member access in scripts remains dot-based (constants.si.mu_B) since
that is ChaiScript's member access operator.

Requested by @lefticus in PR #675 review.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* Address review: C++-style namespace scoping and block declarations

Add :: scope resolution operator for member access (ns::func works
like ns.func). Add block namespace declarations:
  namespace x::y { def func() { ... } }
Functions and variables declared inside a namespace block are added
as members of the namespace, accessible via :: or dot notation.
Namespaces can be reopened to add more members, matching C++ behavior.

Requested by @lefticus in PR #675 review.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* Address review: extract shared make_proxy_function from Def_AST_Node

Namespace_Block_AST_Node was duplicating the entire proxy function
creation logic from Def_AST_Node::eval_internal. Extract a static
make_proxy_function helper so both nodes share the same code path,
eliminating fragile duplication that would drift if Def handling changes.

Requested by @lefticus in PR #675 review.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* Address review: reject non-declaration statements inside namespace blocks

Only def, var, auto, and global declarations are now allowed inside
namespace { } blocks. Arbitrary expressions, assignments, and function
calls are rejected with an eval_error. Added compiled tests verifying
that expressions, function calls, and assignments are rejected.

Requested by @lefticus in PR #675 review.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* Address review: remove -j parameter from unix builds

Ninja handles parallelism intelligently on its own; the explicit -j flag
was causing memory pressure on sanitizer builds. Windows (non-Ninja)
build retains -j.

Requested by @lefticus in PR #675 review.

Subject: [PATCH 47/63] Fix #19: Add enum support (#679)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* Fix #19: Add strongly-typed enum support to ChaiScript

Adds the ability to define enums inside ChaiScript with syntax:
  enum Color { Red, Green, Blue }
  enum Priority { Low = 10, Medium = 20, High = 30 }

Enum values are strongly typed Dynamic_Objects accessed via :: syntax
(e.g. Color::Red). A validating constructor from int is registered that
rejects values outside the defined range. Functions declared with an enum
parameter type (e.g. def fun(Color val)) correctly reject plain integers,
enforcing type safety at the dispatch level.

* Address review: simplify enum implementation

Remove Enum_Access AST node type — reuse Id_AST_Node for enum value
lookups by combining "EnumName::ValueName" at parse time. Replace
std::set with std::vector for valid value tracking (enums are small).
Net removal of ~18 lines.

* Address review: rename to_int to to_underlying, add switch tests

Requested by @lefticus in PR #679 review.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* Address review: enum class syntax, constructor, configurable underlying type

- Change syntax from `enum` to `enum class` (only strongly-typed enums)
- Support optional underlying type: `enum class Flags : char { ... }`
  (defaults to `int` when omitted)
- Replace `from_int` with a constructor named after the enum type,
  accessed as `Color::Color(1)` — the underlying type is no longer
  hardcoded to int
- Use Boxed_Number for type-generic value storage and comparison
- to_underlying now returns the actual underlying type

Note: `Color(1)` syntax is not possible because ChaiScript's global
objects shadow functions with the same name; `Color::Color(1)` is the
C++-consistent alternative.

* Address review: support enum struct syntax alongside enum class

Requested by @lefticus in PR #679 review.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* Address review: update EBNF grammar and cheatsheet with enum documentation

Add enum production rules to the EBNF grammar. Add comprehensive enum
section to the cheatsheet covering syntax, explicit values, underlying
type specification, construction, to_underlying, comparison, type-safe
dispatch, and switch usage. Document that the underlying type must be a
numeric type (string cannot be used) and list all available types.

+## Enums
+
+ChaiScript supports strongly-typed enums using `enum class` (or equivalently `enum struct`),
+matching C++ scoped-enum semantics. Values are accessed via `::` syntax and are type-safe —
+a plain integer cannot be passed where an enum type is expected.
+
+### Basic Definition
+
+```
+enum class Color { Red, Green, Blue }
+```
+
+Values are auto-numbered starting from 0. Access them with `Color::Red`, `Color::Green`, etc.
+
+### Explicit Values
+
+```
+enum class Priority { Low = 10, Medium = 20, High = 30 }
+```
+
+Auto-numbering continues from the last explicit value:
+
+```
+enum class Status { Pending, Active = 5, Done }
+// Pending = 0, Active = 5, Done = 6
+```
+
+### Specifying an Underlying Type
+
+By default the underlying type is `int`. Use `: type` to choose a different numeric type:
+
+```
+enum class Flags : char { Read = 1, Write = 2, Execute = 4 }
+```
+
+The underlying type must be a numeric type registered in ChaiScript. `string` and other
+non-numeric types cannot be used. The available underlying types are:
+
+| Type | Description |
+|------|-------------|
+| `int` | (default) signed integer |
+| `unsigned_int` | unsigned integer |
+| `long` | signed long |
+| `unsigned_long` | unsigned long |
+| `long_long` | signed long long |
+| `unsigned_long_long` | unsigned long long |
+| `char` | character (8-bit) |
+| `wchar_t` | wide character |
+| `char16_t` | 16-bit character |
+| `char32_t` | 32-bit character |
+| `float` | single-precision float |
+| `double` | double-precision float |
+| `long_double` | extended-precision float |
+| `size_t` | unsigned size type |
+| `int8_t` | signed 8-bit |
+| `int16_t` | signed 16-bit |
+| `int32_t` | signed 32-bit |
+| `int64_t` | signed 64-bit |
+| `uint8_t` | unsigned 8-bit |
+| `uint16_t` | unsigned 16-bit |
+| `uint32_t` | unsigned 32-bit |
+
+### `enum struct` Syntax
+
+`enum struct` is accepted as a synonym for `enum class`, just like in C++:
+
+```
+enum struct Direction { North, East, South, West }
+```
+
+### Constructing from a Value
+
+Each enum type has a constructor that accepts the underlying type. It validates that the
+value matches one of the defined enumerators:
+
+```
+auto c = Color::Color(1)       // creates Color::Green
+Color::Color(52)               // throws: invalid value
+```
+
+### `to_underlying`
+
+Convert an enum value back to its underlying numeric type:
+
+```
+Color::Red.to_underlying()     // 0
+Priority::High.to_underlying() // 30
+```
+
+### Comparison
+
+`==` and `!=` are defined for values of the same enum type:
+
+```
+assert_true(Color::Red == Color::Red)
+assert_true(Color::Red != Color::Green)
+```
+
+### Type-Safe Dispatch
+
+Functions declared with an enum parameter type reject plain integers:
+
+```
+def handle(Color c) { /* ... */ }
+handle(Color::Red)    // ok
+handle(42)            // throws: dispatch error
+```
+
+### Using with `switch`
+
+```
+switch(Color::Green) {
+  case (Color::Red) { print("red"); break }
+  case (Color::Green) { print("green"); break }
+  case (Color::Blue) { print("blue"); break }
+}
+```
+
 ## Dynamic Objects
 
 All ChaiScript defined types and generic Dynamic_Object support dynamic parameters

Subject: [PATCH 48/63] Fix #677: Add strong typedefs (#680)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* Fix #677: Add strong typedefs via 'using Type = BaseType' syntax

Strong typedefs create distinct types backed by Dynamic_Object, so
'using Meters = int' makes Meters a type that is not interchangeable
with int or other typedefs of int. The constructor Meters(val) wraps
the base value, and function dispatch enforces the type distinction.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* Address review: add to_underlying function for strong typedefs

Registers a to_underlying() function for each strong typedef that
returns the wrapped base value from the Dynamic_Object's __value attr.

Requested by @lefticus in PR #680 review.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* Address review: expose strongly-typed operators for strong typedefs

Register forwarding binary operators at typedef creation time via a
custom Proxy_Function_Base subclass (Strong_Typedef_Binary_Op). Each
operator unwraps __value from both operands, dispatches on the
underlying types, and re-wraps arithmetic results in the typedef.
Comparison operators return the raw bool.

- Arithmetic: +, -, *, /, % → Meters + Meters -> Meters
- Comparison: <, >, <=, >=, ==, != → Meters < Meters -> bool
- Operators that don't exist on the base type error at call time
  (e.g. StrongString * StrongString -> error)
- Users can extend typedefs with their own operations using
  to_underlying() for unwrapping

Tests cover int-based arithmetic, string-based concatenation, string
multiplication error, comparison ops, type safety of results, and
user-defined operator extensions.

Requested by @lefticus in PR #680 review.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* Address review: conditionally register operators based on underlying type support

Only register strong typedef operators that actually exist for the
underlying type. Previously all operators were added unconditionally,
causing confusing reflection entries (e.g. * for StrongString) that
would fail at runtime. Now each operator is probed via call_match
against default-constructed base type values before registration.

Also adds bitwise/shift operators (&, |, ^, <<, >>) for types that
support them, and expands test coverage for unsupported operator
rejection.

Requested by @lefticus in PR #680 review.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* Address review: register all operators unconditionally and add compound assignment operators

Remove conditional operator registration (op_exists_for_base_type check)
since users could add underlying operators later, and the runtime check was
expensive. Operators that fail on the underlying type now error at call time
instead of being absent. Add compound assignment operators (*=, +=, -=, /=,
%=, <<=, >>=, &=, |=, ^=) via Strong_Typedef_Compound_Assign_Op which
computes the base operation and stores the result back in __value.

Requested by @lefticus in PR #680 review.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* Merge upstream/develop into fix/issue-677-add-strong-typedefs

Resolve merge conflicts with ChaiScript:develop. Upstream added
nested namespace support (#675), grammar railroad diagrams (#673),
and WASM exception support (#689). Conflicts in chaiscript_common.hpp,
chaiscript_eval.hpp, and chaiscript_parser.hpp resolved by keeping
both Using and Namespace_Block AST node types.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* Address review: add strong typedef documentation to cheatsheet

Add a new "Strong Typedefs" section to the cheatsheet covering:
- Basic usage with `using Type = BaseType` syntax
- Arithmetic and comparison operator forwarding
- String-based strong typedefs
- Accessing the underlying value via to_underlying
- Extending strong typedefs with custom operations

Requested by @lefticus in PR #680 review.

+## Strong Typedefs
+
+Strong typedefs create distinct types that are not interchangeable with their underlying type
+or with other typedefs of the same underlying type. They use `Dynamic_Object` internally and
+automatically expose operators that the underlying type supports.
+
+### Basic Usage
+
+```
+using Meters = int
+using Seconds = int
+
+var d = Meters(100)
+var t = Seconds(10)
+
+// d and t are distinct types — you cannot accidentally mix them
+// Meters + Seconds would require an explicit conversion
+```
+
+### Arithmetic and Comparison
+
+Operators from the underlying type are forwarded and remain strongly typed:
+
+```
+using Meters = int
+
+var a = Meters(10)
+var b = Meters(20)
+
+var c = a + b        // Meters(30) — result is still Meters
+var bigger = b > a   // true — comparisons return bool
+
+// Compound assignment operators work too
+a += b               // a is now Meters(30)
+```
+
+### String-Based Strong Typedefs
+
+Strong typedefs work with any type, not just numeric types:
+
+```
+using Name = string
+
+var n = Name("Alice")
+var greeting = Name("Hello, ") + Name("world")  // Name — string concatenation is forwarded
+```
+
+### Accessing the Underlying Value
+
+Use `to_underlying` to extract the wrapped value:
+
+```
+using Meters = int
+
+var d = Meters(42)
+var raw = to_underlying(d)  // 42, plain int
+```
+
+### Extending Strong Typedefs
+
+You can add custom operations to strong typedefs just like any other ChaiScript type:
+
+```
+using Meters = int
+using Seconds = int
+using MetersPerSecond = int
+
+def speed(Meters d, Seconds t) {
+  MetersPerSecond(to_underlying(d) / to_underlying(t))
+}
+
+var s = speed(Meters(100), Seconds(10))  // MetersPerSecond(10)
+```
+
+You can also overload operators between different strong typedefs:
+
+```
+using Meters = int
+using Feet = int
+
+def to_feet(Meters m) {
+  Feet((to_underlying(m) * 328) / 100)
+}
+
+var m = Meters(10)
+var f = to_feet(m)  // Feet(32)
+```
+

Subject: [PATCH 49/63] Fix #116: Add set_file_reader callback for custom file
 loading (#683)

Add a customizable file reader callback to ChaiScript_Basic, following
the same pattern as set_print_handler. When set, the callback is invoked
instead of the default filesystem read, enabling use cases like encrypted
files, in-memory virtual filesystems, or platform-specific file access
(e.g., Android assets). The callback is settable from both C++ and
ChaiScript.

+## Custom File Loading
+
+By default, ChaiScript reads files from the filesystem when `eval_file()` or `use()` is called.
+You can override this behavior on a per-instance basis by setting a custom file reader callback.
+This follows the same pattern as `set_print_handler` and enables use cases such as encrypted
+script files, in-memory virtual filesystems, or platform-specific file access (e.g., Android assets).
+
+```cpp
+chaiscript::ChaiScript chai;
+
+// Provide scripts from an in-memory map instead of the filesystem
+std::map<std::string, std::string> virtual_fs = {
+  {"init.chai", "var x = 42"},
+  {"utils.chai", "def add(a, b) { a + b }"}
+};
+
+chai.set_file_reader([&virtual_fs](const std::string &filename) -> std::string {
+  const auto it = virtual_fs.find(filename);
+  if (it != virtual_fs.end()) {
+    return it->second;
+  }
+  throw chaiscript::exception::file_not_found_error(filename);
+});
+
+chai.eval_file("init.chai"); // evaluates "var x = 42"
+chai.use("utils.chai");      // evaluates "def add(a, b) { a + b }"
+```
+
+The file reader can also be set from within ChaiScript itself via `set_file_reader`:
+
+```chaiscript
+// Override file loading from within a script
+set_file_reader(fun(filename) { return my_custom_read(filename) })
+```
+
+When no custom file reader is set, ChaiScript uses its built-in filesystem reader.
+
 ## Extras
 ChaiScript itself does not provide a link to the math functions defined in `<cmath>`. You can either add them yourself, or use the [ChaiScript_Extras](https://github.com/ChaiScript/ChaiScript_Extras) helper library. (Which also provides some additional string functions.)

Subject: [PATCH 50/63] Fix #690: Apply clang-format consistently with CI
 (#691)

* Fix #690: Apply clang-format consistently with CI

Applied clang-format-19 to all source files to enforce consistent
formatting according to the existing .clang-format configuration.
Added auto-clang-format GitHub Actions workflow (from
cpp-best-practices/cmake_template) that runs on pull requests to
automatically format and commit any style violations going forward.

Subject: [PATCH 52/63] Fix #374: Support nested vector type conversions (#692)

vector_conversion's element conversion used Cast_Helper directly, which
only performs exact type matching. For nested vectors like
std::vector<std::vector<double>>, each inner element is a
std::vector<Boxed_Value> that needs its own conversion to
std::vector<double>. Added a recursive convert_vector_element helper
that detects std::vector value types and converts them from
std::vector<Boxed_Value> before falling back to Cast_Helper for
leaf types.

@@ -90,86 +97,222 @@ same as the Catch name; see also ``TEST_PREFIX`` and ``TEST_SUFFIX``.
     executable is being used in multiple calls to ``catch_discover_tests()``.
     Note that this variable is only available in CTest.
 
+  ``REPORTER reporter``
+    Use the specified reporter when running the test case. The reporter will
+    be passed to the Catch executable as ``--reporter reporter``.
+
+  ``OUTPUT_DIR dir``
+    If specified, the parameter is passed along as
+    ``--out dir/<test_name>`` to Catch executable. The actual file name is the
+    same as the test name. This should be used instead of
+    ``EXTRA_ARGS --out foo`` to avoid race conditions writing the result output
+    when using parallel test execution.
+
+  ``OUTPUT_PREFIX prefix``
+    May be used in conjunction with ``OUTPUT_DIR``.
+    If specified, ``prefix`` is added to each output file name, like so
+    ``--out dir/prefix<test_name>``.
+
+  ``OUTPUT_SUFFIX suffix``
+    May be used in conjunction with ``OUTPUT_DIR``.
+    If specified, ``suffix`` is added to each output file name, like so
+    ``--out dir/<test_name>suffix``. This can be used to add a file extension to
+    the output e.g. ".xml".
+
+  ``DL_PATHS path...``
+    Specifies paths that need to be set for the dynamic linker to find shared
+    libraries/DLLs when running the test executable (PATH/LD_LIBRARY_PATH respectively).
+    These paths will both be set when retrieving the list of test cases from the
+    test executable and when the tests are executed themselves. This requires
+    cmake/ctest >= 3.22.
+
+  ``DL_FRAMEWORK_PATHS path...``
+    Specifies paths that need to be set for the dynamic linker to find libraries
+    packaged as frameworks on Apple platforms when running the test executable
+    (DYLD_FRAMEWORK_PATH). These paths will both be set when retrieving the list
+    of test cases from the test executable and when the tests are executed themselves.
+    This requires cmake/ctest >= 3.22.
+
+  ``DISCOVERY_MODE mode``
+    Provides control over when ``catch_discover_tests`` performs test discovery.
+    By default, ``POST_BUILD`` sets up a post-build command to perform test discovery
+    at build time. In certain scenarios, like cross-compiling, this ``POST_BUILD``
+    behavior is not desirable. By contrast, ``PRE_TEST`` delays test discovery until
+    just prior to test execution. This way test discovery occurs in the target environment
+    where the test has a better chance at finding appropriate runtime dependencies.
+
+    ``DISCOVERY_MODE`` defaults to the value of the
+    ``CMAKE_CATCH_DISCOVER_TESTS_DISCOVERY_MODE`` variable if it is not passed when
+    calling ``catch_discover_tests``. This provides a mechanism for globally selecting
+    a preferred test discovery behavior without having to modify each call site.
+
+  ``SKIP_IS_FAILURE``
+    Disables skipped test detection.
+
+  ``ADD_TAGS_AS_LABELS``
+    Adds all test tags as CTest labels.

+/** \file
+ * Why does decomposing look the way it does:
+ *
+ * Conceptually, decomposing is simple. We change `REQUIRE( a == b )` into
+ * `Decomposer{} <= a == b`, so that `Decomposer{} <= a` is evaluated first,
+ * and our custom operator is used for `a == b`, because `a` is transformed
+ * into `ExprLhs<T&>` and then into `BinaryExpr<T&, U&>`.
+ *
+ * In practice, decomposing ends up a mess, because we have to support
+ * various fun things.
+ *
+ * 1) Types that are only comparable with literal 0, and they do this by
+ *    comparing against a magic type with pointer constructor and deleted
+ *    other constructors. Example: `REQUIRE((a <=> b) == 0)` in libstdc++
+ *
+ * 2) Types that are only comparable with literal 0, and they do this by
+ *    comparing against a magic type with consteval integer constructor.
+ *    Example: `REQUIRE((a <=> b) == 0)` in current MSVC STL.
+ *
+ * 3) Types that have no linkage, and so we cannot form a reference to
+ *    them. Example: some implementations of traits.
+ *
+ * 4) Starting with C++20, when the compiler sees `a == b`, it also uses
+ *    `b == a` when constructing the overload set. For us this means that
+ *    when the compiler handles `ExprLhs<T> == b`, it also tries to resolve
+ *    the overload set for `b == ExprLhs<T>`.
+ *
+ * To accommodate these use cases, decomposer ended up rather complex.
+ *
+ * 1) These types are handled by adding SFINAE overloads to our comparison
+ *    operators, checking whether `T == U` are comparable with the given
+ *    operator, and if not, whether T (or U) are comparable with literal 0.
+ *    If yes, the overload compares T (or U) with 0 literal inline in the
+ *    definition.
+ *
+ *    Note that for extra correctness, we check  that the other type is
+ *    either an `int` (literal 0 is captured as `int` by templates), or
+ *    a `long` (some platforms use 0L for `NULL` and we want to support
+ *    that for pointer comparisons).
+ *
+ * 2) For these types, `is_foo_comparable<T, int>` is true, but letting
+ *    them fall into the overload that actually does `T == int` causes
+ *    compilation error. Handling them requires that the decomposition
+ *    is `constexpr`, so that P2564R3 applies and the `consteval` from
+ *    their accompanying magic type is propagated through the `constexpr`
+ *    call stack.
+ *
+ *    However this is not enough to handle these types automatically,
+ *    because our default is to capture types by reference, to avoid
+ *    runtime copies. While these references cannot become dangling,
+ *    they outlive the constexpr context and thus the default capture
+ *    path cannot be actually constexpr.
+ *
+ *    The solution is to capture these types by value, by explicitly
+ *    specializing `Catch::capture_by_value` for them. Catch2 provides
+ *    specialization for `std::foo_ordering`s, but users can specialize
+ *    the trait for their own types as well.
+ *
+ * 3) If a type has no linkage, we also cannot capture it by reference.
+ *    The solution is once again to capture them by value. We handle
+ *    the common cases by using `std::is_arithmetic` and `std::is_enum`
+ *    as the default for `Catch::capture_by_value`, but that is only a
+ *    some-effort heuristic. These combine to capture all possible bitfield
+ *    bases, and also some trait-like types. As with 2), users can
+ *    specialize `capture_by_value` for their own types as needed.
+ *
+ * 4) To support C++20 and make the SFINAE on our decomposing operators
+ *    work, the SFINAE has to happen in return type, rather than in
+ *    a template type. This is due to our use of logical type traits
+ *    (`conjunction`/`disjunction`/`negation`), that we use to workaround
+ *    an issue in older (9-) versions of GCC. I still blame C++20 for
+ *    this, because without the comparison order switching, the logical
+ *    traits could still be used in template type.
+ *
+ * There are also other side concerns, e.g. supporting both `REQUIRE(a)`
+ * and `REQUIRE(a == b)`, or making `REQUIRE_THAT(a, IsEqual(b))` slot
+ * nicely into the same expression handling logic, but these are rather
+ * straightforward and add only a bit of complexity (e.g. common base
+ * class for decomposed expressions).

Subject: [PATCH 57/63] Fix #493: Allow shared_ptr arguments through
 std::function callbacks (#696)

When ChaiScript wraps a script function in a C++ std::function whose
parameter is a shared_ptr (e.g. const std::shared_ptr<T> &), the
Build_Function_Caller_Helper boxed each argument with std::ref. That
produced a Boxed_Value whose Any held a reference_wrapper<const
shared_ptr<T>> with bare type info shared_ptr<T> instead of T, so
dispatch to a C++ function expecting shared_ptr<T> failed. Detect
shared_ptr parameter types in box() and store them by value instead,
letting Boxed_Value's shared_ptr-aware overloads record the correct
bare type and back the Any with a real shared_ptr.

 / set_state (needed for playground state reset) (#699)

* Fix #693: Add Emscripten/embind bindings for get_state/set_state

The Emscripten wrapper exported only the eval family, leaving JS consumers
with no way to snapshot or restore the singleton ChaiScript engine. The
playground in chaiscript.github.io needs that to reset between runs without
reloading the WASM module. Added handle-based wrappers that hide
ChaiScript::State behind an int registry so JS callers don't have to manage
embind object lifetimes, exported them as saveState/restoreState/releaseState,
and added a native regression test that exercises capture, restore, and
release through the same wrapper functions the WASM binding uses.

* Address review: snapshot top-level locals alongside engine state

ChaiScript::State captures globals, functions, and types but not the
top-level scripting locals created by `var x = ...`. The previous
restoreState therefore left such variables behind, breaking the
playground reset use case and tripping the new test's assertion in
Debug builds (where assert is enabled). Pair get_state with get_locals
in the snapshot so a restore brings back a clean baseline.

Requested by @lefticus in PR #699 review.

* Address review: make ChaiScript engine an opaque handle, drop singleton

Replace the static ChaiScript singleton in the Emscripten wrapper with a
handle-based registry symmetric to the existing State registry. JS callers
now create an engine with chaiscript_create(), pass the resulting handle to
the eval/state helpers, and release it with chaiscript_destroy(). Multiple
independent engines are now possible, and a state snapshot can be restored
onto any engine. Updated the playground HTML and the three native regression
tests to exercise the new API.

Subject: [PATCH 60/63] Fix #633: [Bug] Stack-overflow due to infinite
 recursion in user-defined operator (string interpolation) (#700)

* Fix #633: Bound ChaiScript call stack to prevent native stack overflow

Recursive user-defined operators (e.g. a `string::/=` whose body calls
itself through string interpolation) drove the AST evaluator into
unbounded native recursion and crashed the host process with SIGSEGV.
The dispatcher now refuses to enter a new function frame once
`Stack_Holder::call_depth` reaches `chaiscript::max_call_depth`
(default 256, overridable via the `CHAISCRIPT_MAX_CALL_DEPTH` macro)
and throws the new `chaiscript::exception::stack_overflow_error`
instead, letting both ChaiScript-level `try`/`catch` and C++ hosts
recover from runaway recursion.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* Address review: tighten max_call_depth on MSVC Debug

Windows MSVC Debug builds crashed unit.recursion_depth_protection.chai
with SEGFAULT before the depth check could fire. Windows defaults to a
1 MiB thread stack and Debug builds emit much larger per-frame native
stack usage (no inlining, /RTC, buffer security checks), so 256 nested
ChaiScript calls overflow the native stack long before the dispatcher
reaches max_call_depth. Linux/macOS and MSVC Release pass at 256.

Pick a tighter default (32) only for the MSVC + _DEBUG configuration
that needs it, leaving every other build at the original 256, and shrink
the count_down recursion in the regression test so the bounded path
stays well below every platform's default.

Requested by @lefticus in PR #700 review.

* Address review: use CHAISCRIPT_DEBUG instead of _DEBUG

Switch CHAISCRIPT_DEBUG from a true/false definition to 1/0 so it can
be used in preprocessor #if expressions, then reuse it for the MSVC
Debug guard around CHAISCRIPT_MAX_CALL_DEPTH instead of testing the
compiler-private _DEBUG macro directly. The C++ debug_build constant
keeps its bool value through implicit conversion.

Requested by @lefticus in PR #700 review.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* Address review: restore CHAISCRIPT_DEBUG to true/false for stronger typing

C++ preserves the true/false keywords in #if directives ([cpp.cond]),
so the MSVC Debug guard around CHAISCRIPT_MAX_CALL_DEPTH still works
without weakening the macro to integer 1/0.

Subject: [PATCH 61/63] Fix #612: Allow fun<Signature>(&overloaded) for
 overload disambiguation (#701)

The cheatsheet's "preferred" syntax for binding overloaded free functions,
fun<Ret(Args...)>(&overloaded), only worked on MSVC because the existing
fun<T>(T&&) overload sets T to a function type when called explicitly,
which produces a function rvalue-reference parameter that does not match
a function pointer argument. Standards-conforming compilers (clang, GCC
in some modes) correctly rejected it.

Added two new fun overloads, parameterized on the explicitly-supplied
function-type Signature and using std::type_identity_t to keep that
parameter non-deducible, so they only participate in overload resolution
when Signature is given explicitly. One accepts a free function pointer,
the other a pointer-to-member, enabling both fun<Ret(Args...)>(&free_fn)
and fun<Ret(Args...) cv>(&Class::method) to disambiguate overloads
without resorting to static_cast.

Subject: [PATCH 62/63] Fix #458: Cannot assign string to function that expects
 std::string_view (#697)

* Fix #458: Support std::string_view interop with ChaiScript strings

Register std::string_view as the "string_view" user type with a built-in
implicit conversion from std::string, so a ChaiScript string can be passed
directly to a C++ function taking std::string_view. Adds the reverse
explicit conversion via string(sv) / to_string(sv), plus basic queries
(size, length, empty, data) and comparison operators on string_view.
String-style methods that take size_t (substr, find, ...) are intentionally
not duplicated on string_view: with the implicit conversion in place they
would create dispatch ambiguity for calls like string.substr(int, int).

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* Address review: expand string_view binding with substr/find/[]

Adds substr, find/rfind/find_first_of/find_last_of/find_first_not_of/
find_last_not_of, starts_with/ends_with, and operator[] to string_view_type,
mirroring string_type's search/substring surface so script authors can
traverse a buffer through string_view without allocating.

Sharing method names with string_type creates an ambiguity in
dispatch_with_conversions when the script call needs arithmetic conversion
(e.g. myString.substr(int, int)): both string::substr and string_view::substr
match-except-for-arithmetic, and the existing const/non-const tiebreaker
doesn't apply. Extend dispatch_with_conversions to prefer the candidate
whose first/receiver parameter type exactly matches the actual receiver,
mirroring the deprioritization already in dispatch(). With this in place,
myString.substr(1, 2) still resolves to string::substr while
mySV.substr(1, 2) resolves to string_view::substr (returning a string_view).

Updates the doc comment on string_view_type and adds a compiled test that
locks in both dispatch directions plus the new search/substring methods.

Requested by @lefticus in PR #697 review.
