[Python-Dev] Typing Summit at PyCon US

I'd like to remind everyone that in 8 days, at PyCon US in Cleveland, we'll
have the Typing Summit (the day after the Language Summit). There's still
room to register <https://goo.gl/forms/rG9dVTBbgyBgDK8H2>! So far I've
received just under 20 registrations -- there's room for at least 20 more!
The summit is for both developers and users of static type checkers for

Topics will include (not necessarily in this order):

Michael Sullivan: Annotation growth at Dropbox, and how we used mypyc to
speed up mypy 4x.
Jelle Zijlstra: The future of typeshed.
Jukka Lehtosalo: Modular typeshed.
Ivan Levkivskyi: Typing and mypy usability.
Andrey Vlasovskikh: Incremental static analysis in PyCharm.
Guido van Rossum: Overview of upcoming typing PEPs (544: Protocols; 586:
Literal; 589: TypedDict; 591: Final).

There's also room to discuss more speculative changes to the type system,
especially changes needed to support numpy, such as integer generics and
variadic type variables, and special cases for wrapper functions using
*(*args, **kwds). I'm looking for volunteers to speak about these topics.
