WebImplementations that produce sequences of values typically use asymmetric coroutines. [5] stackful. Each instance of a coroutine has its own stack. In contrast to stackless coroutines, stackful coroutines allow invoking the suspend operation out of arbitrary sub-stackframes, enabling escape-and-reenter recursive operations. move-only http://stackless-coroutine.readthedocs.io/en/latest/Tutorial.html
