- mypy: that's another story, but it's also optional, use it if you want... (my opinion, like in typescript, if I want types I will do it with go or rust)
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.
Long term goal is to create a lightweight Pandas equivalent by and for the Rust community, but with slight differences in focus..."

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.
