Hey, I read that thread just the other week! Fascinating discussion, though I still disagree that generators have the control-flow advantage: while I personally don't see much of a difference, the other developers whom are newer to JS and asyc execution in general have found async/await conceptually simpler, despite the fact it's still compiled down to generators anyway.

You're right, in that it makes little difference in terms of semantics per se, but having implemented both in the application we're working on (which is at just under 10k semicolons, currently) async/await along with how Flummox/Flux implements the dispatcher, it allows you to work with async methods without propgating async through the entire call stack, and lets you think of the runtime as being synchronous-ish. I'm looking forward to finishing this project, as there's a tonne of stuff I want to write up about it; I think the big issue with ES6/7 is that there isn't a lot of "in the trenches" writeups.

Thanks so much for the discussion on esdiscuss by the way, it really helped me understand async execution and control flow in ES6/7.

PS. This is a neat project, HTTP servers with ES7 async/await. Similar in concept to Koa, but using the newer syntax! https://github.com/quinnjs/quinn
