>From http://clojure.org/transients : "Currently only vectors are supported, and note that not all Clojure data structures can support this feature, but most will. Lists will not, as there is no benefit to be had." That appears a bit out of date given these grep results on master: public class PersistentArrayMap extends APersistentMap implements IEditableCollection { public class PersistentHashMap extends APersistentMap implements IEditableCollection { public class PersistentVector extends APersistentVector implements IEditableCollection{ public class PersistentHashSet extends APersistentSet implements IEditableCollection { It looks to me like PersistentTreeMap and PersistentTreeSet have just not yet been extended to support transients. --Steve -- You received this message because you are subscribed to the Google Groups "Clojure" group.
