If you are implying the code should throw an exception synchronously, instead of returning it asynchronously through the error callback then I'm against that proposal. I'm looking at this through a "Promises" lens which says that all errors should be returned through the Promise (or in our case, the callback). I don't see the benefit of asking developers to check for errors in two different places. Gili
