not really, those right now work with any callable, >>> class C: ... def __call__(self, x): ... return 2*x ... >>> map(C(), [1,2,3]) [2, 4, 6] that's why attaching functionaliy as methods is not always the best solution. regards. _______________________________________________ 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
