With type hints, you can get Java (?) code to run EXACTLY the same speed as Java, so Clojure is FAST.
I think there is a simple misunderstanding here. I think, what Rich means, is that if you provide type hints, the methods calls on an object work directly. Otherwise (if the Compiler can't figure out the type of the object) reflection is used, which is slower. This is indeed a feature, as I understand, that other JVM based scripting languages like JRuby or Groovy or so (don't nail me down on specifics, I don't know for sure) use wrapper objects and different methods imposing a runtime hit on performance. So if I have in Java: foo.frobnicate(), then the equivalent hinted (.frobnicate #^Bar foo) will be exactly as fast. This is a different "fast" than comparing an Array with a PersistentVector. But maybe I think too much. So ignore at will. Sincerely Meikel
