I don't think spending too much effort on the compiler at this point is useful. It will eventually be rewritten in Clojure anyway, and Rich has stated that he is more interested in architectural improvements rather than an optimising compiler, for now at least. Of course, if the optimisations really are simple to implement, I don't think patches will be outright *rejected* if you do send them. When it comes to Clojure/java performance comparisons, I think Clojure code is too different from Java to be directly comparable in most cases. And yes, I agree that getting the best performance possible is a chore. Sure, getting an inner loop to produce the same bytecode as the java equivalent *is* possible, but to do so on whole program level would require writing Java in Clojure and a lot of macro trickery to avoid boxing. No-one wants to do that. Still, I wouldn't worry too much. Clojure is still young, and performance is already good enough for many, many applications. -- Jarkko --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Clojure" group.
