I was largely using Racket as a common enough Scheme that I have installed my computer. I wanted an example from another functional language but in an older classical style (I was shooting for the Little Schemer here). I'm quite familiar with Racket's match, somewhere around my blog I even have a "proof" of sorts of using Racket's match to do the famous Haskell quicksort in just as few lines of code. If you really want an ugly rendition I could try and replicate one of the awful JavaScript versions of "map" that uses a for loop, but I thought that might obscure the comparison of operations too much, and the semantics wouldn't be equivalent (linked lists vs. JS arrays).
