Re: [VOTE] True Async RFC 1.6

Hello. Bob Weinand shared an excellent idea about how Fiber can be used together with coroutines without breaking backward compatibility. It is enough to automatically assign a coroutine to a fiber, and then the code inside the fiber will be normalized relative to the Scheduler. Fiber receives the same properties as a coroutine and can be used as a stackful generator. This change makes it possible not to block Fiber, but instead allow it to work together with TrueAsync and be used in cases where stackful generators are needed. A Fiber blocks the execution of the coroutine from which it was started, meaning its symmetric behavior is preserved. Respect to Bob Weinand --- Ed
