Google Dart was designed to build large scale web applications, yet all their demos and example code only includes small applications. That still require quite a lot of code to build.

I don't see any profit of building a application in dart, if you have to create more code your self than you would with a regular HTML5 based application.

As this "Hello World" demo shows, the only thing It's good at is creating bloat and this will probably stay this way until native parsers are implemented.
