Adding type hints to Python source code in the CPython code base has been a controversial issue, which is why I brought it up here.

Prior discussion:

Type annotations in the stdlib

I’d like us to think carefully about this. I agree that this might be nice for “simple” type annotations, where an argument can e.g. only be a str or whatever. But I’d be wary of starting a large-scale project to add type hints in lots of places. As a typeshed maintainer and a codeowner for typing.py, I’m obviously pro-typing. But I’ve also seen how “apparently simple” functions can get very complicated to add annotations for. There will be a lot of functions where we won’t be able to add typ…

As I said earlier, tooling is a less controversial topic.
