I'm learning Scheme so I can program Impromptu (http://impromptu.moso.com.au/) to control my MIDI setup live. I'm having a hell of a time with macros and define-syntax; I have not yet found docs that explain those so I can understand them. I have played around with SBCL and Clojure, and can write macros in those languages. Don't know why I'm having problem with Scheme.
I'm learning Scheme with SICP after a failed attempt at picking up OCaml. I didn't make significant progress beyond writing toy OCaml
and was experiencing some serious culture-shock in my first foray into the functional programming world. After some floundering it became clear that I needed a better introduction to the functional programming mind-set. Purchasing SICP turned out to be an excellent decision.
