I know Haskell, and seeing your example Lisp code makes me completely dumbfounded: the parentheses look 100% redundant to me. What's the point of parenthesizing all expressions like that? Do they work as a replacement for newlines, which are ignored? It looks a bit like C's semi-colons, except twice as bad.
