I use QuickCheck, but it wasn't germane the point I was making so I didn't mention it.

Actually, I did think of using sum when I was computing the length differently, but I made another change and never got back to it. I agree, sum would be better.

I didn't mean to snipe: the "funny" I'm using is in a "cite original sources" mode, which has little/nothing to do with the non-academic world. :)
