Hello,
I was just wondering if you are using the right function. Without
actually trying to run any code, a couple of things pop into mind:
1. alts! can only be used in a go macro.
2. The invocation doesn't look right for alts!.
Perhaps you want something like:
(let [[val port] (async/alts!! [[inner-chan e]]
:default :default
:priority true])
(condp = port
inner-chan (println "did the put")
default (println "failed to put")))
I hope this helps.
Sincerely,
Daniel
