Ghosts work well when you need to use the object identity, such as:

 * `$a =3D=3D=3D $b`  checks
 * `spl_object_id(...)`
 * `SplObjectStorage`

Ghost objects operate at property level, and can only ever work with
concrete classes.

IMO, proxies can operate also at interface level (probably future scope),
and could be expanded to not need a concrete implementation until the
initialization callback is reached.
