I think we need both because an unimplemented method is an error, while an unimplemented rich comparison between disparate types is (usually) not. It could be made to work with one object fulfilling both functions, but then the name would be wrong for one case or the other. -- Neil Cerutti <[EMAIL PROTECTED]> -- http://mail.python.org/mailman/listinfo/python-list
