What about this nodejs async,

May be a replacement until the async is implemented in V8

It's not a replacement at all, and has almost nothing in common with what is discussed here (except the name).

That's the most common node flow control library, and it's awesome, but it's still built on callbacks. With ES2016 you can have an async function return a value you can assign to with =.

Or, short ver: less indentation.
