class TestManager:
def __enter__(self) -> None:

exc_val: Optional[BaseException],

def func() -> int:
with TestManager():
return 1
Mypy will complain about func(), saying it doesn't have a return statement.
tests/__init__.py:16:1: error: Missing return statement
Is this intended?
Note: I also tried class TestManager(ContextManager[None]): just to see if that would help mypy but it didn't change anything.
