Michael's solution works too, but the problem here is that you're calling recur in a way that doesn't make sense. You'd want to replace the call to count-zeros with recur rather than calling both, but it's not in the tail-position, so it can't be TCO'd. Just remove the call to recur and it will work, albeit only for lists small enough to not blow the stack. -Phil -- You received this message because you are subscribed to the Google Groups "Clojure" group.
