I don't think this is good. I'm also a big fan of "no use" but if a package is
designed to be "used" you should not fight this fact. Ada.Strings.Unbounded is
really designed to be "used". You certainly don't want to declare something
like :

   Str : Ada.Strings.Unbounded.Unbounded_String;

Quite a bit of redundancy!

Pascal.
