Add stubs to typeshed

[chadrik]

As per the typshed contribution docs, this issue is to request permission to add attrs to the python typeshed. Also, it doubles as a way to let you know that @euresti and I are ready for you to review #238.

This gives them the opportunity to consider adopting type hints directly in their codebase (which you should prefer to external type stubs).

That...doesn’t really make sense in mypy‘s current Modus operandi, does it?

I believe that is correct. Mypy searches for stubs within a list of paths defined by MYPYPATH, ignores PYTHONPATH, and explicitly advises against pointing MYPYPATH at site-packages. So for all intents and purposes, python's package distribution (i.e. pip) and PEP484 stubs are at odds with each other. Until PEP 561 is complete (slated for 3.7) we have the typeshed.

Well, yolo away then.

[chadrik]

You only YOLO once ;)

Agreed on typeshed being the next step here.

Can this be closed?

[euresti]

All @chadrik needs is for this to say that the maintainers give permission to put it in typeshed. Closing is probably ok.

[hynek]

Permission is granted.
