I wouldn't expect it to work in a `for` comprehension, because that's combining laziness (which uses function thunks under the hood) with the async state machines. In general, you shouldn't do side-effects in a `for`, though I'd be surprised if you couldn't take at the input.
This works (let [ch (clojure.core.async/to-chan (range 10)) ch2 (clojure.core.async/chan 2 (partition-all 2))] (clojure.core.async/pipe ch ch2) (clojure.core.async/<!! (clojure.core.async/go (for [x (clojure.core.async/<! ch2)] x)))) Returning (0 1), but that's probably not what you'd want.
