Unless they were looking at classic classes, why wouldn't they be using the specific Py<Type>_Check() macros? If you want this argument to be taken serious, use Google code search (code.google.com) or a similar source code search engine to find examples that would break. Again, the only envisioned overloading is where the 2nd argument is an ABC. Also, note that PyObject_IsInstance already returns abstract results when the first argument is a proxy instance. -- --Guido van Rossum (home page: http://www.python.org/~guido/) _______________________________________________ Python-3000 mailing list Python-3000@python.org http://mail.python.org/mailman/listinfo/python-3000 Unsubscribe: http://mail.python.org/mailman/options/python-3000/archive%40mail-archive.com
