This sounds fishy to me! Could it be that the Cookbook means that SUPER stops at the first match?

I had to test, and it appears to be the case:

#!/usr/bin/perl -w

package A;

sub new { bless {}, shift }

package B;

sub new { bless {}, shift }

sub blarf { print "B::blarf\n" }

package C;

@ISA = qw/A B/;


sub blarf {
    my($self) = @_;
    print "C::blarf\n";
    $self->SUPER::blarf;
}

package main;

C->new->blarf;

__END__

% perl ~/super.pl
C::blarf
B::blarf
