How mature is ClojureScript these days? I remember people saying it and Clojure on Android was rough when I was exploring Clojure a while back. Does the compiler eliminate unused code from the final output?

Seems to be pretty mature, there are apps in App Store written in it, and there are companies, using it for their front-end (i.e. Prismatic :)).

That's done by Google Closure Compiler in advanced mode.

I'm led to believe the issues with Clojure (and other JVM languages) on Android are due to Dalvik not being as friendly to other languages as the Sun JVM. I don't blame Google, but it's unfortunate.

There are actually games written in Clojure that run on Android quite well. A bit slow to start up, but not nearly as bad as I had expected. Take a look at https://play.google.com/store/apps/details?id=com.friendlyvi... and check out their development blog.
