Anything that depends on the differences in behavior between classic and new-style classes, e.g. multiple inheritance if the inheritance graph contains a diamond, or type(exc) having a specific value (namely, the metaclass for classic classes), or certain broken behaviors (like read-only properties not being really read-only). It's hard to make a complete list. -- --Guido van Rossum (home page: http://www.python.org/~guido/) _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
