It might seem like that, but javascript generator semantics mean that execution pauses at the first yield, and awaits external input before it resumes computation. Also, the framework I described is only partially "hypothetical". [Concur-js](https://github.com/ajnsit/concur-js https://github.com/ajnsit/concur-js) gives you almost the same syntax and semantics. So you can try it out yourself :)
