`a/map` close out channel immediately when any one of inputs closed

Question

(def c1 (chan)) (def c2 (chan)) (def out (a/map vector [c1 c2])) (a/close! c1) (a/<!! out) ;; will hangs until I put item to `c2` or close `c2`

I think the better way is close output channel immediately when any of input channels closed.
