Hey, I'm deeply interested on how one would build a tree consisting of Objects. The following code actually works (which was kinda a surprise). Are they any pitfalls and hidden doors in the tree building + object concept? 
package Node;
use strict;

sub new {
 my $proto = shift;
 my $class = ref($proto) || $proto;
 my $self = {};
 $self->{NODES} = [];
 $self->{TITLE} = undef;
 bless($self,$class);
 return $self;
}

sub title {
 my $self = shift;
 if (@_) { $self->{TITLE} = shift; }
 return $self->{TITLE};
 }
 
sub add {
 my $self = shift;
 push(@{$self->{NODES}},shift);
}
    
sub nodes {
 my $self = shift;
 return @{$self->{NODES}};
}
    
1;

# -------

#!/usr/bin/perl -w

use strict;
use Node;

my $parent = Node->new();
$parent->title("Parent");
my $child1 = Node->new();
$child1->title("Child 1");
$parent->add($child1);
my $child2 = Node->new();
$child2->title("Child 2");
$parent->add($child2);
foreach my $ref ($parent->nodes)
{ print $ref->title; }
