: I really feel that a 'SUPER attribute would make the language more
: useable, and maybe implementors will start providing it.
I actually recommended such an attribute (I named it 'Parent) as part of
the Ada95 revision. My suggestion was struck down for the reason you see here
(you can emulate it with "subtype"). I still think it's a good idea,
even though there's a simple workaround, because it simplifies maintenance
and reduces possible errors (e.g. forgetting to redefine subtype Parent when
the hieararchy changes).
