According to the documentation for 'str': With one arg x, returns x.toString(). So it looks like toString() on a sequence used to return its contents and now doesn't. However, rather than relying on this behavior what you probably should be doing is using 'apply': (apply str (filter even? (range 1 10))) => "2468" If you want commas between those elements, use 'interpose': (apply str (interpose ", " (filter even? (range 1 10)))) => "2, 4, 6, 8" Aloha, David Sletten --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Clojure" group.
