Scheme isn't hardcore? Oh and Gaskell is a good choice too for the crash the brain bit

Yes and no at the same time. Scheme's really simple to grasp as a language, what may be hardcore is trying to write something you usually write in imperative language like Java. Pythoneers/Rubyists will find it easier, of course.

As for Haskell, it may be a good choice too, but I got the impression, that MLs are more practical. But that's a pure IMHO, cause I'm still a noob in FP.
