I read this comment, waited for 10 minutes for smarter people than me to comment. Now I'll bite.
What? Why? Clojure is a JVM language. The ClojureScript compiler _is_ running on the JVM (in Clojure). Why would you want to create a backend for the JVM for a language that tries to match a JVM language as closely as possible - and relies on the JVM for tooling?
I rocked back and forth for minutes. Please explain why you assume that someone considered this and why it wouldn't be nonsense?
