That's like saying that implementing a scheduler using coroutines is silly. Yet people do it all the time. * You may keep moving the goal posts all you want, your original claims were wrong and they stay wrong.

Can't you just say something like "I like coroutines more, they are so minimalist and elegant, and yet they are equivalent in power to cooperative multitasking!". I'd actually subscribe to that notion. But not your overblown claims of objective superiority.

* One has to wonder why so many people crave a scheduler, when they already have coroutines? Maybe because having a scheduler makes certain things easier than naked coroutines?
