Now that I've seen and reviewed KJ's implementation using _PosArgs, I am worried about it, as it looks quite complicated. @Shantanu, do we really need to worry that Callable[P, R] could be ambiguous? If P is a ParamSpec, wouldn't Callable[[P], R] be invalid? ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue42195> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
