Using conj and pop on vectors for stack operations should work just fine. Don't use subvec though; nested subvecs will really start to slow things down. Under some circumstances, lists cache their count, and therefore a list implementation may be just as fast, but I can't remember the exceptions off-hand, so a vector offers more of a promise of the behavior you want. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Clojure" group.
