Allow the use of types.ModuleType

[pkch]

Based on this SO question, I tried this code:

import types
def f() -> types.ModuleType:
    return types

and it failed type check with Incompatible return value type (got "module", expected "ModuleType"). I think names exported in types.* are appropriate for cases like this?

I think this is just a duplicate of #1498

I am closing this now, I also updated the description of your PR to mention the existing #1498

Yup it is... I hope only the issue is a duplicate, not my PR 😆
