I agree except that Clojure is specifically intended to be used functional, and not as OO. Clojure is not pure FP as it does allow state changes (in a controlled way), but that's an acknowledgement that state changes are useful and purity can be, I'll say, difficult. The way Java's OO embraces state changes is not the same principle, and makes things more difficult. OO style is possible in Clojure, but that's not what the language is meant for.
