Well said. I am also really stoked for the possibilities of this as well.
It is a very elegant solution so far. I love the pragmatic approach considering all of the tradeoffs.
I can express what I want such as classes & modules/namespaces and it outputs the same js I would have hand coded for the most part to achieve those concepts.
I saw quite a bit of whining in various places (typical nonsense remarks like oh waa you're ruining js, this and that).
I guess people get emotional about languages, I hope the language designers don't get discouraged.
Very nice stuff so far, and I am really excited about this solution.
