It's weird that they're adding code to the stdlib without type annotations.

Lots of code in the stdlib does not have type annotations. Though I think most popular modules in the std either are annotated or have stubs somewhere.

I know, but I expected that to be restricted only to older modules. I don't expect them to annotate all existing modules.

I don't see why they would introduce _new_ code without annotating it, when that's clearly the trend for 3rd party libraries. From a quick look, it doesn't seem like it would be difficult to type either.

Maybe submit a patch?

The standard library has type hints in the "typeshed" github repo. Please do not submit PRs to cpython to add type hints (I made this error before too:))

Isn't the change for the CLI? That's not accessible from scripts, so that may be why.

Though, I agree that typing everything is good. Especially when combined with a good typechecker like pyright.
