Where did you see that? It would be useful to provide a path or link to the appropriate file at Python's git repo.

@metatoaster I expect it's what they see when clicking on a builtin in intellij/pycharm, because the ide opens a python stub file (which basically just has definitions & signatures for the IDE to parse / recognise).
