I am working on a program that has several hundred constants and I'm trying to figure out a good way to include those via a required file or a used module. I've run into problems and looking for advice.

If I require a file full of constants in g1.inc like

use constant FAILURE_CONF  => 1;
use constant FAILURE_EVENT => 2;
use constant OPEN_REQ      => 3;
use constant OPEN_CONF     => 4;

1;

And use it like

use strict;

require "g1.inc";

if ( 3 == OPEN_REQ ) {
    print "Code is OPEN_REQ\n";
} else {
    print "Code is NOT OPEN_REQ\n";
}
[download]

I receive: 'Bareword "OPEN_REQ" not allowed while "strict subs"'. I had thought for some reason requiring a file is like inserting that code at that spot in the script. Is it a compiletime vs runtime issue?

If I use a module, what is the briefest way to pass my large number of declared constants into the main namespace without retyping everyone of them into @EXPORT?

I await your witty wisdom. :-)
