One incompatibility in current implementations is that
Object.getPrototypeOf(window) in Opera is Object.prototype whereas the rest
have something like Window.prototype (Window doesn't exist in Opera).

An interesting consequence of mutable __proto__ and having the global
variable record be a "regular" object is that mutating its __proto__ has
the same net effect as using `with`.
