Try (set! *warn-on-reflection* true) at your REPL and then evaluating the above. One of the commonest causes of slow Clojure performance is reflection, which can generally be avoided with judicious application of type hints. -- Protege: What is this seething mass of parentheses?! Master: Your father's Lisp REPL. This is the language of a true hacker. Not as clumsy or random as C++; a language for a more civilized age. -- You received this message because you are subscribed to the Google Groups "Clojure" group.
