I'm working on #2171 -- putting map, filter, zip in 2.6's future_builtins. It has been suggested that it would be simplest to just return itertools.(imap, izip, ifilter), which is what py3k/Python/ bltinmodule.c, revision 61356 did.
The advantage of this is that it's really easy and the behaviour seems to be identical. The disadvantage is that the two aren't identical: >>> type(map(lambda x: x, [1, 2, 3])) # Python 3 <type 'map'> >>> type(map(lambda x: x, [1, 2, 3])) == map True >>> type(map(lambda x: x, [1, 2, 3])) # Python 2.6, with the patch <type 'itertools.imap'> >>> type(map(lambda x: x, [1, 2, 3])) == map False Recommendations? _______________________________________________ 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
