> There is very few features of ES6 that are not syntax sugar.

(Weak)Map, (Weak)Set, Symbol, Generators, Promises, Modules, Proxies... these aren't sugar.

So generator, weak references and proxies.

Promises, modules we already had. Native implementation doesn't provide new functionality, just picks winners.

I'm really excited by generators and proxies but those are available in latest version of CoffeeScript already.
