Additional typing specialization

[MikhailArkhipov]

P2 level - Callable, Generator, IO, etc.

We may want to consider throwing in some of these as plain objects in the meantime, just to have them listed in the completion (#1607).

FWIW the new LS we released today has full typing support: https://devblogs.microsoft.com/python/announcing-pylance-fast-feature-rich-language-support-for-python-in-visual-studio-code/

[HuskyNator]

This does not work for Union[List[type], type, None], it just assumes it's List[type]?

This project is no longer actively maintained; consider trying Pylance, which has full typing support.
