yeah.. The one that scares me more, is the chunk in other coffee files. upgrading coffeescript make the code not working anymore

  (a,b) ->
  console.log(a)

Now translates to:
function(a,b) {}
console.log(a)

I think the new version is more correct, but the code that work at some point did not work anymore :-/
I think those are youth issues.
