By the way: Racket is not at all for "programming basics only". Racket, the language, is as rich a programming language as you'd like. Even the Racket team's pedagogy is wide-ranging, from middle-schools to introductory collegiate to upper-level programming languages to graduate-level programming language research.
Hmm, I should rephrase. That was, not so ironically, an over-simplification of what I mean.
When I say basics, I mean you guys get to core CS principles and notions, not basic in the simpleton sense. I see Racket as a very impressive extension of SICP wizardry, and not just the #lang/sicp. I mean building an extensible series of interoperable Lisp and non-Lisp languages for so many disciplines and domain-specific requirements is a ridiculous, daunting. PLT/Scheme Racket is something I stumbled upon when I started to research "Scheme, but modern and coherent" and "natively compiling Clojure."
I have been nothing but impressed with the return to basics means building blocks for everything, from advanced GUI toolkit and continuation based web servers. I wish more people were in the Racket community to light my way with more libraries, but that is really just my laziness.
