Another issue with using process.nextTick() is it ruins the stack trace (which might be fine or maybe even desirable in some cases, but isn't so great for error checking/handling). That can be fixed by using bind(), but at that point we're adding a lot of cruft to the code IMO. (Related gist that shows stack traces: https://gist.github.com/BryanDonovan/6254656).
As a real-life example, I wrote an Elasticsearch client that checks for missing args in fashion I mentioned earlier in this thread (e.g., https://github.com/BryanDonovan/node-simple-elasticsearch/blob/master/lib/client.js#L94). Is that something I need to change?
