What's your question? (Or, if no question, point?) :-)
Totally off topic (and indeed "off-list"..) is that really how ruby
sums a list? How does that work? Doesn't the '*' mean multiply? and
what are the pipe symbols for? (Feel free to ignore these questions. I
should really go look it up myself if I'm so curious..)
