[asottile]

still TODO:

• audit TYPE_CHECKING

I know this is WIP, but FWIW I think you can also remove .travis.yml entirely.

yeah the problem is a good percentage of them have some things that need manual attention (I started with com2ann and then said "maybe later"):

• a lot of them are forward annotations
• some can be refactored as follows:

x: VeryLongTypeNameHere = (
    expression_here
)

=>

x: VeryLongTypeNameHere
x = expression_here

I'm going to be splitting this out into a bunch of PRs so this is easier to merge -- right now it's going to be a real pain to keep rebasing / managing conflicts as I finish things up 👍

This change seems to combine lots of unrelated changes, but overall it seems that most of it is around adding fstrings and type checking.

I would totally support smaller steps of atomic changes, like remove py35 jobs and update python_requires, followed by update pre-commit linters.

Yep, but after I added the comment.
