tldr; type hints in python source are scary. Would reserving them for stub files be better?

I think so. I think PEP 8 should require stub files for stdlib modules and strongly encourage them for 3rd party code. Agreed. I have many of the same concerns as Harry, but I wouldn't have expressed them quite as well. I'm not too worried about actually removing annotations from the core language, but I agree that we should create a strong culture of "type hints go in stub files" to keep source files readable and clean. On that note, I'm not sure "stub" files is a particularly good name. Maybe "type files" would be better? Something that emphasises that they are the correct place to put type hints, not a workaround.

How about "header" files?
