Sorry I was in a hurry. It has many more features for a sync that looks like sync and for other things. It has a cleaner syntax. It supports easy access to multiple callback return values. It has all of the other CoffeeScript features. It seems very obvious if you look at ToffeeScript that it is objectively better. I find it difficult to believe that it isn't getting more attention. Probably just because it doesn't have a web site.
