This pretty much kills the proposal. Calling a "print" function like pprint() should not have a side effect on the object being printed. I'd be okay of pprint() special-cased the views returned by e.g. dict.keys(), but if all we know is that the argument has a __next__ method, pprint() should *not* be calling that. -- --Guido van Rossum (home page: http://www.python.org/~guido/) _______________________________________________ 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
