The module does look very useful, but unfortunately I'm not able to install modules for my scripts to use. Well, more of a guideline than a requirement. The scripts I'm writing will be used on a variety of different machines, which may or may not have anything other than core modules installed (it's almost always limited to just core modules, using ActiveState Perl). So if a module is pure Perl, I can copy the relevant sections into my script (making sure to note where the code came from, of course) and make it stand-alone. But anything that requires a compiler to install is a pretty good guarantee that my script won't be usable by anyone else.
