I've tried porting finger trees to Scheme before, and although it is efficient in an algorithmic sense, I found the constants involved to be so high, performance was very poor. Perhaps it was a fault with my port, but I've become quite skeptical of the value of finger trees. Anyway, I've been satisfied with clojure.lang.PersistentQueue for queues. I often want a priority queue, but John Harrop addressed that need not long ago. Before that, I would sometimes just use Clojure's sorted set. Sometimes I still want a persistent deque, but I haven't needed it quite badly enough to warrant coding one myself. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Clojure" group.
