Variadic run!

[Claudius Nicolae]

run! can eagerly map a function over a coll.

I think it would be nice to support multiple collections, making it an eager version of map.

My particular use case is running a test over two colls.

    (defn check [m1 m2]

      (is (almost= (:x m1) (:x m2)))

      (is (= (:y m1) (:y m2))))

    (run check coll1 coll2)

run is a high performance version of (dorun (map ...)), implemented via reduce which also doesn't support a variadic fn. Probably (dorun (map ...)) is what you are looking for?

Yes, I go by `(dorun (map ...` currently .

I was reading [1] and got the impression that run! is to be preferred, but it seems it's not a full replacement.
