You need to read up a little on modules and "require" in Perl5.

The quick and dirty solution is to use "do" instead of require.  That will
solve your immediate problem, but you'll still be reading the files every
time which might eventually become a performance hit.

What I do when I have things like config files is make actual unique
packages of them.  For example:

(In My/Module.pm)
package My::Module;
# don't use strict here
$foo = 7;

(In some other program)
use My::Module;
print "$My::Module::foo\n";

Honestly though, your example makes it look like you'd be better off with
dbm files and Tie::MLDBM or something.
