I'm not getting you. Whether you call it a "reference to an Object"
or a "reference to a Value" (whatever the difference between those
things might be), it's still a reference.

The reason that nobody would be criticised for saying it, despite
the fact that implementations can indeed pass shared references,
is that the primitive types are all immutable.
