You seem to know your way around coroutines, so I have a few questions for you.
First, std::execution::task doesn't seem to have a WhenAll primitive. How do I track the completion of specific coroutines within a task?
Also, where does the receiver fit into this picture? And what does a sender semantically represent in a coroutine context? For instance, if I'm dealing with Linux signals, would that be modeled as a sender or a receiver?
Finally, is std::execution actually ready for out-of-the-box usage?
