Its often the case that when i write a script, i'll break the code into multiple files that are required by the 'main' file. I'm talking about situations where some of the broken out files arent modules, but they're separated for helping keep the code organized. I think this is a pretty common practice.

Anyway, sometimes i'll want to use the same constants across many of these required libraries. Is the best way to do this to create a package with all the constants in it, export them, and use the constants package in all the support libraries that need them?

I guess this method seems a bit cluttered. Heres a simple example:

# file MyConstants.pm 

package MyConstants;
require Exporter;
use base qw(Exporter);

@EXPORT = qw(C1 C2);
use constant C1 => 'blah';
use constant C2 => 'foo';
1;

# file my_program.pl 
#!/usr/bin/perl
use MyConstants.pm
require 'my_support_lib.pl';
...
# do something with the constants from MyConstants.pm
...

[download]
# file my_support_lib.pl 
...
use MyConstants.pm;
...
# do something with the constants from MyConstants.pm
...

Is this a good way to accomplish this sort of thing?
