Brian> Does anybody have a reason to use a generic (package or

                                        ^^^^^^^^^^^^^^

   ... of the code, not of the variables:

generic 
package P is
   X : Integer;
end P;

with P;
package P1 is new P;

with P;
package P2 is new P;

   Now P1.X and P2.X are two differents variables.
