yeah.. The one that scares me more, is the chunk in other coffee files. upgrading coffeescript make the code not working anymore  <pre>   (a,b) ->   console.log(a) </pre>  Now translates to:  <pre> function(a,b) {} console.log(a) </pre>   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.
