Bug description:
Running importlib.resources.files() without specifying the anchor parameter in interactive REPL in Python 3.12 raises a rather unhelpful error:
>>> import importlib.resources
>>> importlib.resources.files()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib64/python3.12/importlib/resources/_common.py", line 45, in wrapper
return func()
^^^^^^

return from_package(resolve(anchor))

AttributeError: 'NoneType' object has no attribute 'name'It would be nice to return something more helpful. The documentation doesn't mention that this function can raise, so I am assuming that raising AttributeError is not part of the public API?
However, on a locally built Python from current main branch, this call returns a path to Lib/_pyrepl. Even more surprising though is that this also happens when running the OLD REPL with TERM=dumb ./python
❯ TERM=dumb ./python
