Why does Date need private state? AFAICT, it only needs uniquely named
state. Why not do what we've done for many other bits of internal
state that doesn't need to be private: just name it with a unique symbol?
yes (assuming unique symbols are a thing in the end. I think there were
threatened. unique string could work though)
This doesn't work for all internal state of course
yes. I think that in all this discussion, Date is a representant of
built-ins that have private state. WeakMap internals really can't be
exposed as unique properties for instance.
