Interesting link, thanks. But I must admit I have no idea what's going on. 

    sub set_phrase {
        my $self   = shift;
        my $phrase = shift;
        $phrase {$self} = $phrase;
    }
    sub get_phrase {
        my $self   = shift;
        return $phrase {$self};
    }

What does $phrase {$self} do?
