I think this issue appeared previously on typing tracker. The current recommendation is to escape problematic annotations with quotes:

q: 'Queue[int]'

I don't think it will be added to typing, because following this way typing will grow infinitely to include all generics in stdlib.

Another solution may be to add a simple `__class_getitem__` to `Queue` that will just return `cls` (so that we don't import `typing`). Although it will skip all the normal typing checks (so that `Queue[42]` will not raise at runtime), static type checkers like mypy will flag such errors. Guido, what do you think about such experiment?
