Guido van Rossum <gu...@python.org> added the comment:
Well, it's certainly no bug fix, but just as PEP 585 lets us write list[int] instead of typing.List[int], it could be considered useful to be able to write callable[[int, int], str] instead of typing.Callable[[int, int], str]. It's easy enough to make it work so that callable(x) returns a bool but callable[X, Y] returns a built-in subclass of types.GenericAlias (the built-in type). That said, I don't have data about how popular Callable is compared to other types (Sequence/Iterable etc. which will remain in collections.abc). Maybe someone can do some grepping of popular projects? ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue42102> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
