I'm fairly new to node.js, but having done some decent work in AS3/Flex (admittedly years ago) I'm a bit amassed that they didn't take a look how Adobe took on some of these "problems". I think it is a pity that the don't have callbacks for onError and onResult for instance. It would be easy to do and code would look nicer and with less noise. I suspect there are other niceties that could be learned from AS3/Flex and async/ event loop programming.
