One way to avoid these warnings being generated in the first place is not
to "use" core.async, but "require ... as" it, e.g.:
(ns message-bus.latam
(:require [core.async :as a]))
The down side is that then you must prefix all uses of symbols in
core.async with the alias "a/".
You can also :exclude the symbols that give the warnings. Then you do not
need a prefix for most symbols in core.async, except for the ones that you
excluded, which will need a prefix.
There is a ticket requesting a change in the current Clojure behavior, but
it has not been commented upon by anyone, so there is no evidence whether
it will ever become part of Clojure:
