Lazy-seq is tricky to use. It's also often not necessary. If you can implement yours in terms of map, reduce, or something else you should do so. But sometimes all you can think of is a way to generate items in a loop, often a stateful loop. Someone posted a macro here a few weeks ago that is supposed to be easier to use than lazy-seq. Search the forum for "lazy-seq" and see if you can find it. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Clojure" group.
