Type could not be determined because it refers to itself

[augustelalande]

I'm not sure I can describe what's happening better than just sharing the code.

MRE:

from enum import StrEnum


class Foo(StrEnum):
    A = "A"


for _ in range(2):
    baz: dict[Foo, int] = {}

    if Foo.A in baz:
        ...

    for _ in baz.values():
        ...

Output:
