I might be missing something, but isn't this basically covered with the
enumerable flag? And that brings us back around - if we only had unique
symbols and we defined the property using the symbol, and made it
enumerable false, would it still be private? Am I missing something obvious
(I probably am)? I know this is more work, but it would be more orthogonal.
Sugar could be added to class to make this better.
