Perl objects are hashes

• Hashes are commonly used for objects

• Keys are member data names, values are member data

        if ($self->{TYPE} eq 'octopus') {
          $self->{tentacles} = 8;
          $self->{hearts} = 3;
          $self->{favorite_food} = 'crab cakes';
        }

• Every member data access requires a hash lookup
