Paths with hyphens do not correctly work with mypy; trying to run mypy on such a path results in a "not a valid package name" error. This is not aligned with e.g. importlib.import_module, and so is probably a bug in mypy. To Reproduce $ mkdir beep-boop $ touch beep-boop/__init...

Consider the following valid Python 3 code: class A(): pass class B(): def __init__(self): self.a = A b = B() class C(b.a): pass Actual behavior: Mypy will report Name 'b.a' is not defined on the line class C(b.a):. Expected behavior: No error reported by Mypy. ...
