I don't think this is really a question of implementation - it's a design question of "should". The current behaviour is reasonably sane. But if you're confused by it, there's a simple solution: Don't reference the same "thing" more than once on the LHS. ChrisA -- https://mail.python.org/mailman/listinfo/python-list
