Ok, I've seen it now! Am I correct that the statement in the spec that 
"No storage associated with an Unbounded_String object shall be lost 
upon assignment or scope exit" means somebody else has done all the work 
of handling the underlying access types and I don't need to worry? I 
note that it does have a free method, but presumably that's just for 
early release before it goes out of scope. If I'm right then yes, I can 
completely eliminate access types in the code I've done on my exercise 
so far. Hurrah!
