Ok, so if they check for it, they might as well handle it. Or maybe they shouldn't even check for performance reasons? Then no error, and it's up to the programmer to decide which looping construct to use. _Ron _______________________________________________ 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
