You have to be quite careful to avoid "holding on to the head" of the sequence when you do this sort of thing. You can create a sequence of lines from a Reader (clojure.core/line-seq or duck-streams/read-lines) but you have to be careful that you deal with the sequence only through lazy functions such as "map", without keeping any references to the start of the sequence itself. -SS --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Clojure" group.
