Almost.... and Ember can mostly work with that last time I checked.

The missing piece is delegation though, i.e. you can't define a catch-all getter/setter and many Ember.*Proxy classes/mixins (e.g. http://emberjs.com/api/classes/Ember.ObjectProxy.html) rely on that. Like most Ember Controllers are delegating data state to a model, and are supplementing app state/behaviors on top.

ES6 Object Proxies fixes that.

But I'm liking how fast the Ember team has been including ES6 transpilers into directly in to Ember App Kit. So we may be writing more regular JSy looking property dot notation, like Angular, soon enough. And get all the benefits of UAP.

(By the way, for coffeescript fans, ember-script sort of does this for you: http://emberscript.com/)
