Examples shouldn't use typing_extensions imports for stable typing features #1986
Description
Description
There are a few code examples in the docs which import things from typing_extensions that are by now available in Python's typing standard library module:
List
typing/docs/guides/unreachable.rst
Line 57 in 3149e8c
typing/docs/reference/generics.rst
Line 655 in 3149e8c
... and 4 more occurrences in reference/generics.rst.
typing/docs/reference/protocols.rst
Line 75 in 3149e8c
... and 4 more occurrences in reference/protocols.rst.
typing/docs/reference/quality.rst
Line 43 in 3149e8c
It probably makes sense to use typing imports for all of these instead, possibly with the typing_extensions alternative mentioned.
How to fix?
What is the policy for these? Should they just be replaced with bare typing imports or something more like
from typing import Protocol # or from typing_extensions for Python < 3.8?
I haven't seen the latter in any of the other imports, which just import from typing without comment (EDIT: at least not in the code itself, but usually it is mentioned as an alternative for older versions somewhere around the code), but who knows...
