Brian Hulette updated BEAM-9012:
--------------------------------
    Description: 
mypy [made a decision|https://github.com/python/mypy/issues/604] to allow init methods to omit `-> None` return type annotations, but pytype has no such feature. I think we should include `-> None` annotations for pytype compatibility.
