Why not allow the spread operator to appear earlier (still just once though) in ArrayPatternList in http://wiki.ecmascript.org/doku.php?id=harmony:destructuring?

Yeah, I think we need it (at least if to make the destructuting feature, then to make it completely). CoffeeScript has such a middle-destructuring feature also: http://jashkenas.github.com/coffee-script/#destructuring
