alt Hacker News> "Asynchrony" is a very bad word for this and we already have a very well-defined mathematical one: commutativity.
I don't think it's sufficient to say that just because another term defines this concept means it's a better or worse word. "commutativity" feels, sounds, and reads like a mess imo. Asynchrony is way easier on the palette
commutativity is also not correct, because 1) it means way more things than just temporal ordering and 2) there are cooky temporal ordering schemes you can come up with (interleaving multiple async/awaits in weird time-dependent ways) which aren't really describable in the simple mathematical notion of commutativity.
