cute :-)

Does this actually work?  I assume dart_library needs to be concatenated in
here?

yeah, it doesn't work yet :|

what we need here is module support, either ES6 or the nodejs `require` style.
If we did that transform then it would work:

#!/usr/bin/env iojs
let dart = require('dart_runtime/dart');
let core = require('dart/core');

// code here ...


ultimately covered by https://github.com/dart-lang/dev_compiler/issues/34
