I agree with the point on CL libraries, which is truly sad after this many years. But Lisps like Clojure address this formidably by integrating deeply with the JVM and actually also Python. Im not sure his code is idiomatic SBCL but it could be written more succintly and functionally by most LISPers. To the point on static/dynamic typing, I disagree. But its a discussion thats been going on for so long that Ive concluded its mostly a matter of taste. For Clojurians who like static typing, Spec packs a big punch without removing flexibility. Still, Haskell is pretty great but Im more efficient in Clojure, Your mileage will vary.
