Janus/Ada actually does neither -- the bounds are stored separately, and
belong to neither. (The memory used is allocated separately if needed.)
Indeed, I don't think you can store the bounds with the array for
slices, so I think your analogy is incorrect (there is nothing like
slices for tagged types, of course).
