That's all I can find in stdlib 🎉

I think these can also return object, like with the asyncio one.

Oh, I've also missed cases like assertRaises / etc

[sobolevn]

I will double check that I've covered everything tomorrow with a better regex (that counts possible multiline func definitions).

Thanks a lot for your reviews! 👍

protip: reformat the codebase with black --line-length=999999999 to make greps and codemods simpler.

[sobolevn]

Idea: maybe we don't need to type assertRaises?

Some people might send some intentionally bad arguments 🤔
