The last (triangle-numbers) is recursive, but without loop/recur this consumes stack. Instead of defining a function, you might want to use def. This seems to work: (def triangle-numbers (lazy-cat [1] (map + (iterate inc 2) triangle- numbers))) cheers, gert --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Clojure" group.
