Greetings Avout,

Why am I getting this error:

#!/usr/bin/perl

use strict;
use warnings;

my $person = My::Person->new( 'neil', 'watson' );
print 'Name is', $person->given_name();

package My::Person;

use strict;
use warnings;
use Class::InsideOut qw[public readonly private register id];

# declare the attributes
readonly  given_name   => my %given_name;
readonly  surname      => my %surname;

# object constructor
sub new {
   my $self = shift;
   register( $self );
   $given_name{ id $self } = shift;
   $surname   { id $self } = shift;
}

1;

$ ./indsideout.pl 
Use of uninitialized value in hash element at ./indsideout.pl line 23.
Use of uninitialized value in hash element at ./indsideout.pl line 24.
Can't locate object method "given_name" via package "watson" (perhaps 
+you
forgot to load "watson"?) at ./indsideout.pl line 7.
