For me, the key problem is that a class object reference has the same

refers to. This is sometimes what you need, but more often you want a
non-shared, mutable reference to a const/immutable/shared object.

You can achieve this with pointers for arrays, structs and primitive
types, but not with classes because a class pointer is just a pointer to
a reference.
Hence the hack that is Rebindable!().

Oh, and you _can_ achieve pointers to classes, but what you normally use are
references, which do have the problem of not being able to be split between the
reference and referent types.

So how do you get a pointer to an object? Taking the address of an object reference gives you a pointer to the reference, not the object, which is fair enough. As far as I know there isn't a way to get a pointer to the object itself, and even if you could, how do you use such a thing?
