Nice. If I had a bit more time at the moment I'd try writing this in Haskell just as an exercise to see what it would look like in a real functional language. :) I might try it a months or so time, once I've finished exams.

I have to agree with you that all programmers should try their hand at all the programming styles, even if it's just so they can experience the joy of functional programming first hand!

Cheers!
