why is this language change and extra complication to parser logic even necessary? why can't we just advise people to follow the jslint way of using the "ignore" binding, instead of changing the language spec yet again for no good reason?

e.g.

/* jslint */
try {
...
} catch (ignore) {
}

things like this gives off the impression that changing the javascript language spec is cheap, which is not something people like me want to encourage.
