heycam, bz, what's the conclusion on this? Should I stick [Unforgeable] on 
the interface to make everything in that interface unforgeable? Should I 
define a valueOf and make just that, the toString serializer, and href 
unforgeable? Something else?

Incidentally there's also a request to mark the 'location' attribute 
itself (on Document, presumably also the one on Window) unforgeable:
