I'm still thinking about this but I'm leaning towards specifying that
defineMethod creates a new function and leave it up to implementations to
optimize trivial cases where that is unnecessary like:
Object.defineMethod(obj, "foo", function () {super.foo()});
Also, Object.defineProperty used to define a accessor property get or set
function probably should also have this semantics. Because 'super' is new that
seems like an upwards compatible extension.
