I have been playing w/ cross compiling a language to Dart. There is no bytecode[1] which actually makes it a tad easier. Dart does give you method_missing semantics w/ noSuchMethod. Granted a runtime method lookup table, if you were building Ruby on Dart, would lose the compilation optimizations on dynamic methods, but you'd still get them w/ the explicitly defined ones (I guess the same way as JRuby). When Dart has more runtime compilation abilities (beyond just spawnUri) I think it will be a great target for dynamic languages. 1 - http://www.dartlang.org/articles/why-not-bytecode/ http://www.dartlang.org/articles/why-not-bytecode/
