Personally, this is what I would do when creating and importing my module. Creating module:

package YourModule;
require Exporter;

use strict;
use vars qw(@ISA @EXPORT @EXPORT_OK);
@ISA = qw(Exporter);
@EXPORT    = qw(get_id AnotherSub);
@EXPORT_OK = qw(evenMoreSubs justOneMore);

Under @EXPORT place all of the subroutines that will use in all your other modules, and then call it like so:

use YourModule qw (:DEFAULT);
use strict;

my $id = get_id();

If you include the :DEFAULT tag, it will use all subroutines from @EXPORT. This should do what you're looking for. Cheers!
