If you're trying to get people in the habit of writing sum(x, "") instead of "".join(x), I fear that they'll try sum(x, " ") instead of " ".join(x), and be sadly disappointed. Frankly, I've had enough of this exploration of alternative definitions for sum(), and think it is perfect as it is. -- --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
