simply by making all attributes primitive operations.

However, attributes of like T'Image (X) should be replaced with X'Image.
You don't need to mention T if 'Image is primitive.

If we go a little further, we will notice that Image is doubly dispatching
on its argument of T and the result of String, which should be from a class
that includes Wide_String, Unbounded_String etc.
