 Replying to [ticket:11065 goldfire]:
 > I've been doing functional programming for some time, and I still like
 to look at examples to make sure that I'm getting my `foldl` and `foldr`
 straight.

 This video by Tony Morris is great: [http://vimeo.com/64673035 Explain
 List Folds to Yourself]. It's 48 minutes, but you'll never mix `foldl` and
 `foldr` up again.
