I always thought it would be cool if CoffeeScript's generated JS code added Closure Compiler annotations, such as @const and @param types. Let the user minify/optimize the generated JS using their favorite tools.
Thanks! I hadn't seen this "UberScript" before, though I was kinda hoping the Closure annotations could be inferred "for free" without changes to the CoffeeScript language. <:)
