I did forget this. My simplicity involved getting rid of [Unforgeable]
interface members, so obviously we can't do that then.
But I don't like having to add a valueOf operation to the IDL. So maybe
we can a separately named extended attribute on the interface that
results in valueOf being unforgeable.
What about other functions from Object.prototype, by the way?
toLocaleString, watch, hasOwnProperty, etc.? If there are a bunch of
properties (that don't correspond to IDL members) that need protecting,
maybe handling it in [DefineOwnProperty] is the simplest thing to do.
