The problem this solves is very real-world. Consider a Perl class hierarchy in which a class Child inherits from classes Mother and Father:
package Child; use base qw(Mother Father);
If both Mother and Father have DESTROY methods, what happens? Under normal Perl semantics, only Mother::DESTROY would be called, since it's the left-most, depth-first method encountered during the dispatch. But failing to call one (or more) of an object's inherited destructors is not correct behaviour. Hence the need to be able to call all of them:
package Child; use base qw(Mother Father); sub DESTROY { $_[0]->EVERY::DESTROY }
