I'd say more "effort and stubbornness" is required to get a Java/C# app out the door in decent time compared with Clojure. There was a study not long ago in which Clojure won hands down for least number of bugs and lines of code. I think Rich Hickey got a few things right so don't write-off Clojure too hastily. There's also Clojure Spec round the corner so you'll be able to have your types and eat it too. Win, win surely, no?
