Oh, right. I saw "paralell" and the brain hit autopilot. And I think you CAN improve on your fn a little bit. This should do the trick
(map + (range 1 5) (range 11 15)) The mapping fn itself will be applied to as many arguments as you have collections. Since + is variadic, it will do the job nicely.
