Hi, folks:

Assumed I have an existing OO module(i.e. Example::Model which might be from other contributors), and I want to add some new methods(not override the existing methods). Besides subclassing, are there any more practical ways to do this from the "design pattern(i.e. GOF)" point of view.

Sample code by subclassing: 
package MyApp::Example::Model;
use strict;
use base 'Example::Model';

sub new {
    my $class = shift;
    return bless Example::Model->new(@_), $class;
}

sub mymethod1 {
      ####;
}

sub mymethod2 {
      ####;
}

1;

Thanks a bunch,
