If you define module with constants you should use Exporter to export them into the namespace of your script. For example:

package MyConstants;

use base qw(Exporter);

our @EXPORT = qw(CONST1 CONST2);

use constant CONST1 => 12356;
use constant CONST2 => 'xxx';

1;
[download]

In this example all constants are exported by default but you may want to make it optional. See Exporter documentation for details.

Simple script which uses these constants:

use MyConstants;

use strict;
use warnings;

print CONST1;
[download]

All I get is bare words.

What leads me to idea that you should use strict and warnings. It would catch this as error.
