I'm actually somewhat sad that they added the two in front of Scheme. I took an intro to CS course there the summer before heading to college and it was taught in Scheme. The teacher literally taught us the language the first day and then, from there on out, it was learning different techniques through mostly computer labs. Prior to that, my only programming experience had been in TI-Basic, so it was an eye-opening experience to realize that programming was more than just an ordered set of instructions. If I hadn't had that experience, I think I might have learned the wrong lesson when my college CS courses dumped C on me.

I'm not sure about Haskell as a beginner's language, but I consider Scheme to be almost ideal for that purpose since it's so easily digestible.
