It's only a personal side project and I have a good handle on the untyped modules in question, so in the end I suppressed most of the errors with `# type:ignore` and friends.

I'd reconsider that if I was doing more than the odd bug fix on the project. I still like Python, and started using type hints early, but there's enough added friction to make me question using them in the future.

I imagine on big projects the benefit is clearer.
