[Python-Dev] Product function patch [issue 1093]

[Guido van Rossum]

Actually, if you use Google code search, you'll find that multiplying
the numbers in a list doesn't have much use at all. After summing
numbers, joining strings is by far the most common usage -- which is
much better done with the str.join() method.

(PS. I rejected the issue; product() was proposed and rejected when
sum() was originally proposed and accepted, and I don't see anything
to change my mind.)
