small mypy fixes

[asottile]

mypy is very far from passing, but it did point out a few small cleanups that were doable

Great.
Would be nice to have some mypy config already in setup.cfg maybe, or share it here.

[asottile]

agreed, but even with no config there's 1000+ errors right now, I hope to reduce them slowly, eventually

I was using pre-commit try-repo https://github.com/pre-commit/mirrors-mypy and then fixing the crashes

mypy --check-untyped-defs --ignore-missing-imports src/ has 275 issues "only".. ;)

[asottile]

I was also looking at testing since it's useful to validate those calls as well, I might've also had --check-untyped-defs as well I forget
