Dart: Build HTML5 Apps Fast

This article is rubbish. I don't see how these examples will help me build HTML5 apps. Pardon the rage but I'm also tired of class-oriented language showing me a Point or Dog class as an example when I never encounter them in real-world code. This article is just a list of features that might or might not help you with building HTML5 apps and has no compelling argument. Also this: "The Dart project ships a lightweight editor". Since when is Eclipse lightweight ?

Instead, show me how you actually build an HTML5 app with dart. How do you layer your code to keep things manageable. Are you using MVC or something else. Is dart interoperable with existing libraries like Backbone, Modernizr or Google Closure or do I have to port these things. How do you actually support modern HTML features like CSS3 transitions, canvas, websockets, postMessage, localStorage, ... Am I back to "compile time" flow breaks or are you taking care of that in the background. These are the questions that if answered properly would have made a nice article.
