I don't like coffee script for the same reason - it adds extra processing steps and runs different code than I write in the browser. While it cleans things up, I personally haven't worked on a Javascript project that would benefit from what I see as only incremental improvements to "cruft," which can be just as easily implemented with functions and continuations/monads.
