var {p, q} = o; short for var {p:p, q:q} = o; where o = {p: 42, q: true}. /be

Want this for JS1.8 (JS2/ES4 proving). /be

This added side-trip is easy, if you know the territory already ;-). /be

Warming up a bit with a small patch, hence elevated priority. /be

Comment on attachment 295144 [details] [diff] [review] implementation Incomplete, need consensus from Ecma TG1 based on http://bugs.ecmascript.org/ticket/111#comment:3. /be

The only forward progress to report is approval of destructuring shorthand and the desire to separate object initialiser shorthand that mirrors the destructuring shorthand into a separate bugs.ecmascript.org trac ticket. I don't favor such a "structuring" shorthand at the moment, so don't plan to implement it. Since the destructuring shorthand is approved, I would like to finish this bug by adding the necessary post-parsing AST check for lvalue context. /be

Comment on attachment 299869 [details] [diff] [review] shorthand is for destructuring only (not "structuring" aka object literal) I only skimmed the decompiler changes. Do those JS_ASSERTS want to be LOCAL_ASSERTs?

Finally put together https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Destructuring_assignment which contains info on destructuring in the light of ES6. Marking this as dev-doc-complete.
