Clojurescript-to-native was my first thought too. I think where it will break down is the threading model though. Crystal, for example, threw Ruby's threading model out the window, went with channels, and is now working on an implementation of parallelism. Native JS is a great idea, but we've got to get these languages leveraging the CPUs they're on if we really want fast native code.
