IME, most clutter from async logic in JavaScript, however it's dressed up, only happens at all because of implementing something that is fundamentally sequential and synchronous using the wrong tools for the job. The slide "A JS-er's lament" was a great demonstration of how fundamentally broken the current JS model is.

Put another way, the obviously missing pattern to me is to just move the concurrency up to the level of having multiple threads, and then use synchronous interfaces for synchronous operations. Now that Web Workers are starting to become more widely supported, I don't understand why we aren't heading for synchronous APIs as fast as humanly possible.
