  Yeah, Bob. This is one of the first things one encounters in the
  early stages of learning Ada 95.  

  I have been writing, for some programs, something such as:

         function Get return T'Class;

  and then, for the declaration:

         X : T'Class := Get;

  to ensure compilation.

  The next trick is to decide how to implement function Get. This turns
  out to be quite useful for some situations.

  But then, my guess is that you already do this too.
