Do you have a more practical example. Something where the real
"simple" version was not only too slow, but couldn't in fact be made
effecient without fundamentally rewriting it? I'm sincerely curious
because I've been thinking about this problem lately but don't have
enough real-world Common Lisp experience under my belt to have a lot
of good examples, one way or the other.
