@gsnedders I'm having some fun learning more about mypy. I'm not sure it's worth annotating all of wptserve, but the reason I started was because I found it very hard to guess what the types of some arguments in request.py were. But starting from the "leaf" files results in less cascading errors.

Is there an approach to incrementally improving type coverage that you took for other bits that I could copy?

By and large I used pyannotate (though we probably want monkeytypes at this point) to generate type annotations based on what we're actually using, then started editing them till mypy was happy.

@gsnedders thanks, I saw tools like that mentioned in mypy docs, should maybe give that a try then.
