Yes; moreover, I find it misleading and almost a case of false advertising when such succint code is demonstrated without so much as a footnote mentioning the enormous performance penalty of converting a String into a sequence of Characters and then calling a higher-order function on it. The proper way to advertise Clojure is this: in Java you have little choice but write verbose, performant code; in Clojure you can go both ways and for most cases the overhead won't be the main bottleneck. But, at all times, do keep in mind the consequences of your choice of idiom. -- You received this message because you are subscribed to the Google Groups "Clojure" group.
