"use es6"; Any plans for such a mode?

Thanks for the links, those cleared up pretty much what I had in mind.

On the other hand that means typeof uint8 won't return a primitive 
value, right? Meaning typeof uint8 should return "object", so a 
theoretical Polyfill (or binding in my case) should have the prototype 
pointing to Object?

global.uint8.prototype = Object; // ?
