I whole-heartedly agree here, because people who start learning python (like me some time ago) usually learn that it's bad to test for __call__ (can't remember where I read about that though), and that we should always use callable() to be on a safe side. When I first heard that callable() was going to be removed I kinda panicked myself, it's good to know that at least there's still a way to be sure that object is callable or not... _______________________________________________ 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
