This is /really/ bad design. If you want such operators they would need to
be defined like this:

  TValue = record
    ...
    class operator Initialize(var aRec: TValue);
   class operator Finalize(var aRec: TValue);
    class operator Copy(constref aSource: TValue; var aDest: TValue);
  end;
====== code end ======
