Would you mind updating the "typing" package on PyPI now to contain
something useful? Thanks.

Hello all,
I am pleased to announce that I am accepting PEP 484 (Type Hints).
Given the proximity of the beta release I thought I would get this
announcement out now, even though there are some (very) minor details
to iron out.
(If you want to know the details, it's all at
https://github.com/ambv/typehinting)
I hope that PEP 484 will be a benefit to all users of Python.
I think the proposed annotation semantics and accompanying module are
technically sound and I hope that they are socially acceptable to the
Python community.
I have long been aware that as well as a powerful, sophisticated and
"production quality" language, Python is also used by many casual
programmers, and as a language to introduce children to programming.
I also realise that this PEP does not look like it will be any help to
the part-time programmer or beginner. However, I am convinced that it
will enable significant improvements to IDEs (hopefully including
IDLE), static checkers and other tools.
These tools will then help us all, beginners included.
This PEP has been a huge amount of work, involving a lot of people.
So thank you to everyone involved. If I were to list names I would
inevitably miss someone out. You know who you are.
Finally, if you are worried that this will make Python ugly and turn
it into some sort of inferior Java, then I share you concerns, but I
would like to remind you of another potential ugliness; operator
overloading.
C++, Perl and Haskell have operator overloading and it gets abused
something rotten to produce "concise" (a.k.a. line noise) code.
Python also has operator overloading and it is used sensibly, as it
should be. Why?
It's a cultural issue; readability matters.
Python is your language, please use type-hints responsibly :)
Cheers,
Mark.
