Clojure is nice, although I didn't use it in production. But it is Java deep underneath (so not completely homoiconic) and comparing to CL there are restrictions, albeit mild. For some specific tasks I might have preferred it (until CL catches up with concurrency support). But in general CL gives you more freedom.
