Which brings me to the title of my post. Now that it seems as though ES3.1 will be embraced by all the browser vendors moving forward (and will likely be the implemented iteration of JS for at least a little while), I wondered what sorts of features might still make it into ES3.1 before the spec was closed.
Half-wishing, half-hoping, I threw the idea of codifying noSuchMethod into the discussion on the ES discussion group. As expected, Brendan Eich replied that it was probably too late to add a feature like this into ES3.1 at this time.
Anyone who's messed with Ruby for more than just a simple Rails app understands the power of method_missing, and getting it into ES3.1, which would mean it would make it into future versions of Firefox, Safari, and IE, would be sweet indeed.
