Maybe something like:
#----------------------------------------
package Zoo::Animal;
use strict;
1;
sub new {
my $class = shift;
my $sref_oid = Zoo::Zoo->_gen_oid();
my $self = { _oid => $$sref_oid, @_ };
bless $self, $class;
print "Animal initialised\n";
return $self;
}
#----------------------------------------
package Zoo::Camel;
use strict;
use base qw( Zoo::Animal );
sub new {
my ( $class ) = @_;
my $self = $class->SUPER::new(
_type => 'camel',
_color => 'grey',
_legs => 4,
_humps => 2,
);
print "Camel initialised\n";
return $self;
}
#----------------------------------------
package Zoo::Lama;
use strict;
use base qw( Zoo::Animal );
sub new {
my ( $class ) = @_;
my $self = $class->SUPER::new(
_type => 'lama',
_color => 'white',
_legs => 4,
);
print "Lama initialised\n";
return $self;
}
I don't know if I agree with your Zoo::Zoo 8-)
package Zoo::Zoo;
use UUID;
use lib '.';
use base qw( Zoo::Animal Zoo::Camel Zoo::Lama );
This seems to say to me that a Zoo::Zoo is an Animal, a Camel or a Lama - I would have thought the Zoo is more like a container of Animals, rather than an actual beastie?
