To me this application screams destructuring. Assume you want to (reduce + ...) a collection of sequences. I'd lead off with a simple vector mapping operation, and the reduce over the following sequence like so:
user=>(reduce (fn [[acc-x acc-y] [x y]] [(+ acc-x x) (+ acc-y y)]) (map vector [1 2 3] [4 5 6])) [6 15] Take your problem and adapt accordingly :) On Jun 11, 3:59 am, Nathan Sorenson <n...@sfu.ca> wrote: > Is there a way to fold over multiple sequences, in the same way that > 'map' can apply a multi-parameter function over several seqs?
