Brett Cannon <br...@python.org> added the comment:
I just realized one problem with this is it explicitly requires subclassing the ABC while os.PathLike is supposed to represent a protocol (before typing.Protocol was a thing). So why is it bad that in the example class B is considered a "subclass" of os.PathLike by implementing the protocol? Since it implements the expected protocol what exactly is being lost by not checking for an explicit registration or subclass? ---------- nosy: +levkivskyi _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue38878> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
