Thanks, I'm going to have to take a long hard look at that and the repo. I've just spent a couple of weeks abstracting over async in Swift [0] and where I ended up looks a lot like that - to the point where some of the primitives have identical type sigs (mainly because the patterns used here are not novel - promise/future, async/await, etc). Be great to see this as a core language feature! At least now we can see stuff coming, I had just finished writing unit tests for my OAuth library when Apple rolled an implementation into iOS. [0] I'm aware of PromiseKit and co (and read a bunch of their sources), but I didn't feel like I had a good conceptual grasp on their implementation until I could create something similar and understand how it works and how to use it to solve my actual problems. Often I'll bin my own implementation afterward and use an extant library, so this is almost - but not entirely - quite unlike NIH. Edit:punctuation
