This is a great feature, that Ecmascript 6 already has.

Would that be not something for the Isolates? Perhaps generating boilerplate code when using yield in a method would instead return an Isolate that then would be called by additional boilerplate code induced into the caller based on the generator interface?

Isolate based solutions may evolve, but not in this form.
