I'd call this interpretation indisputable unless I saw jashkenas himself disputing it. In many ways, CoffeeScript is just JavaScript, minus a whole ton of redundant key-tapping.
The more languages I learn, the less I care about syntax and the more I care about being able to express solutions to problems. In that respect, then, CoffeeScript has been no help to me whatsoever, since semantically, it's no different than JavaScript.
