reduce() came as part of the contributed code that also added lambda, filter
and map to Python 1.0. I don't think I've seen a program using Python's
reduce() that wasn't made both faster and clearer by replacing it with a
loop; the same isn't true of filter and map; lambda can be argued either
way, but with the special twist that people arguing in favor of it are
usually thinking of some other language <wink>.
