Hi Fellow Monks, I was playing around with OO perl and i wanted to test if i could replicate __str__ operator method in python with Perl OO. So i created a trivial code to test it out. The code doesn't throw any error, however, i don't get any output either. 

#!/usr/bin/perl
use v5.22;
use overload '""' => 'stringify';
use Data::Dumper;

package oo_test{
    
    sub new{
        my $class = shift;
        my $self = {};
        bless $self, $class;
        return $self;
    }
    
    sub getter{
        my $self = shift;
        while( my $line = <DATA> ){
            chomp $line;
            $self->{$.} = $line;
        }
        return $self;
    }
    
    sub stringify{
        my $self = shift;
        return join(" ", values %$self );
    }
};

package main;
my $test = oo_test->new();
$test->getter();
print $test->stringify;


__DATA__

I'm sure that i'm making some mistakes. I'd like to admit that my OO perl is bit shaky.
