Thank you folks.

To answer some question in reply
a) I have about 500 some constants
b) Yes the plan was to use these constants for "stuff like thing "3" in this array means "name".
This is not the right approach for that?
c) Yes I am currently using the Exporter for this. Here is the code (The recipe to export all symbols is a modified version of a reply that I came across in a different post here at perlmonk) 
package MyConstants;
require Exporter;
@ISA = qw(Exporter);
our @EXPORT = do {
                    no strict 'refs';
                    keys %{ __PACKAGE__ . '::'};
                 };

use constant VAR1 => VAL1;
use constant VAR2 => VAL2;
#--- 500 more of these
1;

Each of the other modules module1.pm, module2.pm, module3.pm then have 
use MyConstants;
