Any error handling that forces me to add extra lines into my code is one I see as too obstructing. First and foremost, asynchronous exception handling and propagation, and "long" stacktraces that go with it, should be a core part of the JavaScript language, and I'm personally waiting for that to happen at some point. In the meantime, the best solution I was able to come up with is "LAEH2". See it here: https://github.com/ypocat/laeh2
