Use recent version of Perl

Before we go on learning about Object Oriented programming in Perl, let's mention a small improvement you can get when using a relatively recent version of perl.

Starting from version 5.36 that was released on 2022-05-28 we can write

use v5.36;

or

use 5.036;

and that will already turn on both strict mode and warnings and it will also include all the features that came with that version, including the say function.

So if we can require that our code will run on a perl version 5.36 or later then we can replace these 3 rows:

use strict;
use warnings;
use feature 'say';

with a single use-statement.
