No, that's not how you would do it in Ada95.  In Ada95, you would use
a generic operation:

  generic
     with procedure Process (E : in out ET);
  procedure Generic_Update (V : in out VT; I : IT);

For reasons I don't understand, many developers convert Ada05
anonymous access subprogram parameters to named access types when back-
porting to Ada95, which is completely wrong, because then you wouldn't
be able to nest the declaration of the process subprogram.
