Another issue with this is, the routines and the framework become tied together. The routines need to know the proper additional protocol to work with that framework, and they also can't be used with any other framework.
An interesting thing about yield-from is that once you have it, the interface between the generators and the framework reduces to the iterator protocol, and there's really only *one* obvious way to do it. This means it may become feasible to have a single coroutine scheduler in the standard library, with hooks for adding various kinds of event sources, so that different libraries handling asynchronous events can work together, instead of each one wanting to be in charge an run its own event loop. -- Greg
