In a inside-out implementation, you need to a way to identify the object that you are working with. The only difference between different objects of the same class are their addresses. by using refaddr we can uniquely identify our objects and hidden the variables in each object from each other.

A very short example

package Foo::Bar; use Scalar::Util qw(refaddr); my %var; sub get_var { my $self = shift; return $var{ refaddr( $self ) }; } sub set_var { my $self = shift; my $value = shift; $var{ refaddr( $self ) } = $value; return 1; } # Not completely sure that this is correct. sub new { my $class = shift; return bless \my($anon_scalar), $class; }

Take a look at Class::Std or Damian Conway's Best Practices on the concept.

    [hippo]: I always wonder how well the Asterix books work in other languages given that maybe 80% of the humour is some sort of word-play. How far do the translations differ?
    [karlgoethebier]: hippo: Study the sources ; -) http://www.asterix .com/die-buecher/ die-asterix- mundart-reihe/
    [choroba]: Perl to the rescue!
    [Corion]: hippo: At least for the German translation, the wordplay is translated as well
