Am I missing something?

Inside Perl 5, a reference only has one slot to associate it with a class. You can replace that association by blessing the reference into a different class, but there's only ever one class associated with a reference.

I don't know what object system you're thinking of, but this is how Perl 5 has worked since the beginning. Test it and see:

package Grandkid; use parent 'Kid'; sub new { bless {}, shift } package Kid; use parent 'Parent'; package Parent; sub inherited_method { 'Yep, inherited!' } package main; use Test::More 'no_plan'; my $gkid = Grandkid->new(); isa_ok( $gkid, 'Grandkid' ); isa_ok( $gkid, 'Kid' ); isa_ok( $gkid, 'Parent' ); is( $gkid->inherited_method(), 'Yep, inherited!', 'method inherited fr +om grandparent' ); done_testing();
