To clarify: I have been looking for something along these lines because my company is looking to invest heavily into Clojure. We come from a Java/JVM environment, and we are very happy with it, but we have to ship a "beacon" to appliances. This means: Java on the server, GWT or JavaScript on the browser, and perl/C on the beacon. With Clojure / ClojureScript / ClojureGo we could have the same programmers moving between the three environments, and it would be a major win for us. Clojure might not be perfect, but we still would be able to write any critical code in the host language.
