This does not use async/await "colored" functions:
Thanks, yes, that's my point. I'm not convinced by async/await as a technique. I'm finding the "non-blocking fibers" approach much preferable in practice.
They both have their own place. If you're writing code where you care about thread identity, like a GUI code or using a native thread for various reasons and you want specific control, async/await gives you that control. If you don't care about thread identity and just care about pure throughput, pre-emptive is less cognitive load up until the work stealing starts to matter.
