And I'll add to this: *Copy and paste* the original code to craft this
output statement. I recently was trying to figure out a problem, and
retyped to create the output statements... and I didn't make the same
typo, so it worked fine. For some reason, my eye didn't notice the
error, and I couldn't understand why the intermediate results were
correct and the overall result was wrong. (And no, it wasn't the kind
of 'wrong' that results in a nice tidy exception. It just resulted in
wrong results.)
