Oops, sorry, I am mistaken about this.

Right now, value_ind calls coerce_array, which calls coerce_ref.
So, if you have a reference to a pointer, Value.dereference will end up
dereferencing the pointer.
So, if your patch went in, it would be an incompatible change.

I think you will have to have a new method for this instead.
