There are many functions that operate on sequences which are not built into Clojure's "for" macro. Perhaps you want partition: user=> (partition 3 1 (range 5)) ((0 1 2) (1 2 3) (2 3 4)) This could then be destructured with for if you want: user=> (for [[a b c] (partition 3 1 (range 5))] (- c a)) (2 2 2) > 3.

Besides (comment ...) there is also ; and documentation strings stored as meta-data attached to function vars. boot.clj has all but the first of these. --Chouser --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Clojure" group.
