SETL in turn took them from much earlier standard notation in set theory, related to the oddly named (but not universally so named) "axiom of comprehension". genexps were more directly taken from Icon, but tying them into Python's iteration protocol is a powerful twist not directly present in Icon. _______________________________________________ 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
