Does the dev team have any plans to provide support for using ES6 Module Loader's ability to add on-the-fly compilation/transpilation for converting from dart to javascript at runtime? This would be a neat way to allow javascript projects to use existing dart code, and could also improve the REPL experience for projects that don't use pub serve. I also think this would fit in nicely with the just announced "Dart for the entire web" strategy/paradigm shift.
