It depends on your goals. If the goal was to create a new language well Dart has done that. If the goal was to give web dev some of tools of app dev (static typing, classical restricted OOP, better speed) I don't think Dart was the right answer specifically because I don't think it's got much chance of getting adopted by other browsers. The practical solution IMO would be the CLR. Why? Because if Google had chosen the CLR they'd instantly have brought Microsoft and IE along with them at which point Mozilla would probably be pulled in if kicking and screaming. That seems to me the most pragmatic solution but sadly Google is unwilling to do that for whatever reason.
