Almost right. The iterate function is an infinite sequence generator, so (count (iterate f x)) will never return.
If you want the iteration to terminate when cond is false (as in your original example), you're looking for this: (count (take-while cond (iterate (fn [[a b]] ... [new-a new-b]) [init-a init -b]))) Happy hacking! -- You received this message because you are subscribed to the Google Groups "Clojure" group.
