It may be due to my background, but that I understand or feel a lot better :). I suppose as time passes and I see more and more Clojure code that will change anyway. I know this is going very offtopic, but why did you use "let" define "in-matrix?" instead of a defn? That's another thing I'm finding a little bit confusing... in F# you just use "let" for everything", in Haskelll you don't type anything. So, why would it be more appropiate?
