And a minor style nit that I don't think has been mentioned yet:
Lowercase module names are reserved by convention for use as compiler directives ("pragmas") by Perl (e.g. strict, warnings, sort). Granted this was probably just a name you came up with off the cuff for testing, but it's better to get in the habit of capitalizing your package names. It's akin to not using $a and $b as variable names even in one-off code; sometime down the road you're going to wind up spending a couple of hours chasing down a "bug" that isn't.
