Thanks for this. I don't know when I will make the time to learn new languages, but I think I've decided that when I do, one of the array programming languages is where I'll focus. This page seems like as good a place to start as any.

The xkcd "light saber" thing made lisp seem appealing to me a few years ago, but after a brief intro to the array languages, now I think they're much more deserving of that comparison.
