I always find it funny when people consider Lisp a functional language. Lisp is really multiparadigm: it's as easy to write imperative code as it is to write functional code. I worked at ITA in their Lisp code for two years. It's mostly imperative, and only uses a functional style where you would in other languages, e.g. using recursion to walk a tree.
