Honestly, after trying MyPy for a bit, I'm probably going to gradually type. There's some metaprogramming constructs (notably certain class decorators) that are not expressible in the type system, for one. This makes packages like environ-config unusable.

But most importantly, `def foo(lst: list, idx: int):` is fine in 95% of cases. Most of the time, you don't need to go full Java, full verbosity. Document the most important elements - you're taking in a list and an int - and move on.

Good luck finding a pandas or scipy implementation for go or rust :-/

EDIT: That one looks like it's not being worked on actively. Here's a reddit thread with more ideas. Weld looks interesting.

And Arrow looks like a new project Wes McKinney is contributing to.

Right. Projects can always choose not to enable asyncio. I don't see what the problem is. Right tool for the job, &c.
