No, you should use [id://NUMBER] to link to other nodes. See What shortcuts can I use for linking to other information?.

The preferred thing to export from a module is a subroutine. Or, alternatively, you can switch to the object oriented approach.

Shared.pm:

package Shared;
use warnings;
use strict;

use Exporter qw{ import };
our @EXPORT_OK = qw{ test_val test_list };


sub test_val { "hello world\n" }

sub test_list {
    ( [ 'Shadow',  'Blinky' ],
      [ 'Speedy',  'Pinky'  ],
      [ 'Bashful', 'Inky'   ],
      [ 'Pokey',   'Clyde'  ],
    )
}

__PACKAGE__

test.pl:

#!/usr/bin/perl
use warnings;
use strict;

use Shared qw{ test_val test_list };

print test_val();

for my $pair (test_list()) {
    print "@$pair\n";
}

Object oriented

Shared_OO.pm:

package Shared_OO;
use warnings;
use strict;

sub new {
    my $class = shift;
    bless { test_val  => "hello world\n",
            test_list => [ [ 'Shadow',  'Blinky' ],
                           [ 'Speedy',  'Pinky'  ],
                           [ 'Bashful', 'Inky'   ],
                           [ 'Pokey',   'Clyde'  ],
                         ],
          }, $class
}


sub test_val { shift()->{test_val} }

sub test_list { @{ shift()->{test_list} } }


__PACKAGE__
[download]

test_oo.pl:

#!/usr/bin/perl
use warnings;
use strict;

use Shared_OO;

my $o = 'Shared_OO'->new;

print $o->test_val;

for my $pair ($o->test_list) {
    print "@$pair\n";
}
