I think the real question here (in all seriousness) is:  Why you think
you need this?  It's really an implementation detail whether an
immutable object (a particular one, that is) can be copied to make a
unique object with the same value.  Since immutable objects cannot in
any way be changed, it makes no difference whether or not two references
have reference to the same immutable object, or have references to two
unique immutable objects with the same value.
