¹ coroutines are not zero cost

That depends. I've done some investigation into the Coroutines TS described in n4134. For coroutines whose scope is strictly limited to the calling function, they can be implemented with zero cost (no dynamic allocation and comparable assembly output). The expository code that Phil provided certainly falls into that category. Thanks
