"Efficiency" is a function of timing requirements. GNAT's Unbounded_String is so 
inefficient that we have a soft real-time application that makes extensive use 
of Unbounded_String and has no problem meeting its timing requirements.

Unbounded_String is perfectly reasonable for many situations; worrying about 
"efficiency" before encountering timing constraints is premature optimization.
