JavaScript proposal: destructuring assignment

That link is to a really old ES4 discussion. The proposal for ES6 is at http://wiki.ecmascript.org/doku.php?id=harmony:destructuring and has now been incorporated in the draft ES6 spec.

A form of this will probably be in ES6:

CoffeeScript implements this syntax, and, of course, it's extremely awesome.

I think this is a great proposal. I would be very happy to see destructuring assignment in JS. In every other language I've used that supports this (Erlang, Clojure) it is a big win.

This would be extremely handy. At the moment I'm sometimes even writing

   (function (a, b, c) {/**/}).apply(null, packed);

to emulate destructuring.

Cool, if it gets widespread implementation.

Had to read a ways down to see an example to confirm, in simple terms, that this would mean you could make function calls such as:

( a, b, c) = f();

like you would in Perl / Python / Ruby. (not so good at decoding BNF while I'm sipping my first cup of coffee in the morning...)

This is something that's been in Firefox's JS way back since FF 2.0.

Seems like half of the comments are from 6 years ago, am I missing something?
