The platform has the capability to make a structured clone of an object (and primitives): http://www.whatwg.org/specs/web-apps/current-work/multipage/common-dom-interfaces.html#safe-passing-of-structured-data This is used for history traversal as well as passing data between global objects that cannot reach other synchronously (e.g. a document and worker environment). Should this capability become part of JavaScript? When new objects such as Map are defined or such an object is implemented by a JavaScript library they can then "automatically" participate in the structured clone fun.
