This auto-unwrapping for internal slots used to be part of an early iteration of direct proxies < http://wiki.ecmascript.org/doku.php?id=harmony:direct_proxies#wrapping_irregular_objects> but was not carried over into the ES6 spec. IIRC, mainly because just forwarding any internal slot access endangers the encapsulation properties of membrane-like use cases.
