I know it, and I deliberately reject it. Having access types in a pkg spec is 
poor design. Delegating the associated memory management and all its 
opportunities for error to the pkg client is very poor design.

If access types are used, they should be hidden and encapsulated with their 
memory management. This makes it easier to get the memory management correct. 
Since this is what using Unbounded_String does for you, I think it's better to 
use it than to expend extra effort doing something similar.
