Hmm, I'm still missing something. It seems a good lesson, but
practically speaking, it doesn't help me any more than saying "write
efficient programs". What could I have looked for in the original code
to predict it may be leaky? Is there a way of thinking about this that
can help me stop hitting space leaks like this?

BTW, I really do appreciate the help. I've been amazed at the level of
effort put forth by the Haskell community as a whole to help out
newcomers.
