I just watched (mostly) the CppCon talk you posted elsewhere. The coroutine approach is really interesting, but I'm confused as to how it's different. According to a source I found[1], the way coroutines are implemented is that a new stack is created on the heap and it moves back and forth between that. Isn't that the same case here? Is the compiler level implementation(as opposed to boost, as in the linked reference) different in some way?
