[issue43006] Changed behaviour of inspect.signature() in Python 3.10

[Zac Hatfield-Dodds]

Zac Hatfield-Dodds <zac.hatfield.do...@gmail.com> added the comment:

And I promise this is the last one:


    import inspect
    import typing

    def f():
        A = typing.TypeVar("A")

        def same_type_args(a: A, b: A):
            assert type(a) == type(b)

        print(inspect.signature(same_type_args))
        print(typing.get_type_hints(same_type_args))

    f()


$ python3 t.py 
(a: ~A, b: ~A)
{'a': ~A, 'b': ~A}

$ python3.10 t.py 
(a: 'A', b: 'A')
Traceback (most recent call last):
  ...
NameError: name 'A' is not defined


My apologies to everyone involved here; I'm looking forward to postponed 
annotation evaluation, appreciate all your work on this, and regret that I have 
such bizzare bugs to report <3
