differently knowing it doesn't work in straight-forward way.

Hi,
I needed reversed(enumerate(x: list)) in my code, and have discovered that
it wound't work. This is disappointing because operation is well defined.
It is also well defined for str type, range, and - in principle, but not
yet in practice - on dictionary iterators - keys(), values(), items()
Ok thanks for explaining. I will proceed by trying it with typeshed.
Best Regards,

and sufficient code - then perhaps modifying mypy is a reasonable
price to pay.
Perhaps this particular case can be just patched locally by PyCharm
/JetBrains, but what is a general solution to this class of problems?

alright, so would an import under TYPE_CHECKING guard be an option? like:
from typing import TYPE_CHECKING
if TYPE_CHECKING:
from .process import ProcessPoolExecutor
from .thread import ThreadPoolExecutor
Perhaps we can have both clarity and performance.
and would
indeed be an improvement?
