It sort-of comforms to existing syntax as well as semantics.BTW, if you use var instead of let, if already works out of the box (in FF11 firebug console; just tried), so why include as if it already is there, albeit in different form?
We implemented destructuring years ago to implementor- and user-test ES4 proposals. They did not forbid duplicates. That's all.
Nothing normative in experimental Firefox implementation features, of course. You cite them as "already [there]" and that's true but it doesn't govern what goes into ES6.
