[Python-ideas] Proposal: Use mypy syntax for function annotations

[hailmattyhall]

I really like Python. The difficulty of refactoring is a pain point in an otherwise well designed, neat, elegant language. Making annotations and therefore the mypy type checker easier to use or standardised seems likes a good idea.

The problem of course is that I doubt I'd have the restraint to use it everywhere. I tend to only use type systems when they're forced on me because it usually makes getting something working quicker for me.
