If you know you're dealing with an iterator x, then after a, b, c, *d = x, d would simply be x, so all you really need is a function to get the first n items from x. > I'm suggesting, that: > > - lists return lists > - tuples return tuples > - XYZ containers return XYZ containers > - non-container iterables return iterators. How do you propose to distinguish between the last two cases? Attempting to slice it and catching an exception is not acceptable, IMO, as it can too easily mask bugs. -- Greg _______________________________________________ Python-3000 mailing list Python-3000@python.org http://mail.python.org/mailman/listinfo/python-3000 Unsubscribe: http://mail.python.org/mailman/options/python-3000/archive%40mail-archive.com
