I found information on the constructs that you used, james2vegas, that confused me in Exporter under "Selecting What To Export."

1. A leading underscore on a subroutine name (_someSub) is just a convention to denote subroutines that are internal and are to be used only in the module.
2. ModuleName::someSub is just another way to call a subroutine without having to export it explicitly using our @EXPORT or our @EXPORT_OK.

These things, while minor, are nice to know for my future writings. I will start adding leading underscores to my internal subroutines, since it is a great visual aid. I might also start using ModuleName::someSub when a module of mine has only one or two subroutines. Thanks for showing me these shortcuts! Cookies! :)
