I once considered and rejected this syntax since another logical interpretation would be that any positional arguments are accepted but *ignored*. > Utterly magical to anyone not already familiar with the use of *args, though. But so would any other newly invented syntax, probably, so that doesn't count heavily. Would *None be too bizarre? -- --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
