Hmm, which maybe is not any kind of solution for your question, since it
uses require, which you as you already mentioned cannot be used from a
utility namespace to your main namespace, or else you would create a
dependency cycle.
Clojure/Java has "alias" that might help in such situations, but
ClojureScript does not.
