In a way that is somewhat like you say, namely on a partial
object when it is needed only partially:
T.comp_1: allocated and possibly initialized
S.comp_2: not even allocated
overriding
procedure Foo (X : in out S) is
begin
null;
end Foo;
may "validly" become:
alloc comp_1
jump s.foo
s.foo:
ret
Lousy, but it may "work", even when, without optimization,
some "non-existing junk" is copied for X (if it's not by ref).
Not that I want that! Just imagine the outcome should the
arbitrary location happen to be volatile…
