Didn't we discuss making the [[DateValue]] immutable when a Date object is non-extensible? I see this isn't currently in the ES6 draft. Also, thinking about it now, that seems like quite a one-off hack.
It also brings up the question of, for example, should freezing a Map cause [[MapData]] to be frozen? I think the argument for [[MapData]] and [[DateValue]] is the same, either way. Similarly, what about freezing a RegExp? Should that not prevent `regexp.compile()`?
