Is the return value ignored? Currently there will be a fatal error if return statements (with values) are used in the generator. In the future I'd like to use the return value as the result of a yield from / yield* expression, as it is currently done in Python and JavaScript. This is particularly useful if you are delegating control to another coroutine. This way you can for example break down a coroutine-based parser into several functions (instead of having one big ugly function).

Generators require that the execution context is suspended in some way and we have to that control only over userland code, not internal C code.
