it's really unfortunate clojurescript is not written in javascript (or clojurescript, like coffeescript compiler is written in coffeescript ). I wanted to integrate a lisp to a toy jsbin app (https://mparaiso.github.io/playground/), but no way, right now i'm using outlet. See the use case? clojurescript is never going to be big in javascript land if one cant compile it in the browser.
