False positive F811 when using TYPE_CHECKING

[phil65]

For following code

from typing import TYPE_CHECKING:
...
if TYPE_CHECKING:
    from x import y

...

if __name__ == "__main__":
    from x import y
    ...

Error F811 gets reported, which should not be the case I think.
Thank you for this great tool!

Thanks for the issue! This indeed looks incorrect. Since this is just a small example, I'm curious why you're using this pattern in the real world?

Regardless, it seems like from x import y should be allowed in a new scope if the previous import was in an if-type-checking block.

You would expect the following to get reported still, right?

from typing import TYPE_CHECKING:

if TYPE_CHECKING:
    from x import y

from x import y

Yes, I would expect that to get reported.
I am often using the if __name__ == "__main__": section for testing purposes, that´s why I am using this pattern.

This no longer gets triggered (in the next version).
