I was being a little loose in my description. Ranges always produce chunked seqs via seq: => (chunked-seq? (range 10)) false => (chunked-seq? (seq (range 10))) true `range` returns a lazy seq, which "guards" the chunked seq. Lazy seqs are never chunked themselves (otherwise, "proper" laziness would never be possible) but the seqs they provide are always aligned with the chunkiness of whatever lies beneath the lazy seq: => (chunked-seq? (seq (lazy-seq '(1 2 3)))) false => (chunked-seq? (seq (lazy-seq [1 2 3]))) true - Chas -- You received this message because you are subscribed to the Google Groups "Clojure" group.
