Not if you read the PEP. It doesn't explicitly say what should happen. I want to standardize on raising ImportError. The PEP itself has two ways of signaling an error; find_module() returns None instead of raising an error to signal it can't do something while path hooks raise ImportError. I just want to be as explicit as possible. -Brett _______________________________________________ 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
