Just for fun... And I'm more of a dog fan, too. :)
#!/usr/bin/perl
use strict;
use warnings;
{
package Dog;
sub new {
my ( $caller, $dog ) = @_;
my $class = ref($caller) || $caller;
my $dogs = {
NAME => $dog,
};
bless $dogs, $class;
}
sub name {
my $self = shift;
( @_ ) ? $self->{NAME} = shift
: return $self->{NAME};
}
}
{
package Litter;
sub new {
my ( $caller, $list ) = @_;
die "not an DOG ref" unless ref($list->[0]) eq "Dog";
my $class = ref($caller) || $caller;
my $litter = {
DOGS => $list,
};
bless $litter, $class;
}
sub dogs {
my $self = shift;
( @_ ) ? $self->{DOGS} = shift
: return $self->{DOGS};
}
}
my $dog1 = Dog->new('Strider');
my $dog2 = Dog->new('Bella');
my $litter = Litter->new([$dog1, $dog2]);
for ( @{$litter->dogs} ) {
print $_->name . "\n"
}

Are you posting in the right place? Check out Where do I post X? to know for sure.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

Want more info? How to link
or How to display code and escape characters
are good places to start.
