I think '__metaclass__ = whatever' affects only the creation of classes that would otherwise be old-style classes? > You can't alter classes which you don't control or create in your code. I remeber I've seen an implementation of import_with_metaclass somewhere on IBM's developerworks. I didn't quite undersntad it though. -- damjan -- http://mail.python.org/mailman/listinfo/python-list
