Defining complex.__complex__ and bytes.__bytes__ would not solve anything, because >>> issubclass(int, SupportsComplex) False >>> issubclass(float, SupportsComplex) False >>> issubclass(bytearray, SupportsBytes) False >>> issubclass(memoryview, SupportsBytes) False If SupportsComplex and SupportsBytes are just for "has __complex__/__bytes__ method", they are virtually useless. If their meaning is "can be converted to complex/bytes", it is different story, and it should be fixed be adding subclasshooks which check existence of alternate methods (__float__, __index__, supporting the buffer protocol). ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue24234> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
