Are there any plans for a coffeescript/python implementation of Dart? Could that be done as a preprocessor?

As trivial as that sounds, that is part of what has hindered its adoption. I seem to remember reading about the Dart team learning that many early adopters were not c++/java people but Pythonista's. You'd think they would have adapted to that.

There's kind of a Python-To-Dart translator:
