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

> 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

> C++, Perl and Haskell have operator overloading and it gets abused

> 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 :)
