"...I was suggested to use a role for this...

Not a bad idea. Why don't you give it a try?

P.S.: Little addendum: Years ago i wrote this little sketch for Lady_Aleena to illustrate what was my idea/understanding of a plugin:

package MyClass;

use Class::Tiny qw(something);
use Role::Tiny::With;
use feature qw(say);

say q(package ) . __PACKAGE__;

with qw(MyRole);

1;

package MyRole;

use Role::Tiny;
use feature qw(say);
requires qw(something);

say q(package ) . __PACKAGE__;

around 'something' => sub {
    print q(Long John Silver said );
    uc &{ (shift) };
};

1;


#!/usr/bin/env perl 

use strict;
use warnings;
use MyClass;
use feature qw(say);

say q(package ) . __PACKAGE__;

my $object = MyClass->new( something => q("I reckon i settled you.") )
+;

say $object->something;

__END__
