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 :)
