If what you want is a list of words that could be easily re-used among a lot of projects you could create a function that would return your list, however you want it. Put the function in a required library, and require it in any program that needs it. For instance the file could look like this:

#!/usr/bin/perl -w
use strict;

sub seven_dwarves_names {
   return qw(sleepy happy grumpy dopey sneezy bashful doc);
}

1;

Assuming that file is called keywords.pl, and is in the @INC path, a program that uses them could look like:

#!/usr/bin/perl -w
use strict;

require "keywords.pl";

...
my @dwarves = seven_dwarves_names();
...

Of course you may want your keywords in a different manner, such as hash keys or something else. Have the shared function return the data however you want!
