If it works properly, don't sweat the warnings.
As a general rule, you should only worry about your warnings (use warnings;), since a lot of modules (like Archive::Zip) have comprehensive test suites (which they usually pass with flying colors), but aren't exactly warning-safe (-w makes them talk excessively).

MJD says "you can't just make shit up and expect the computer to know what you mean, retardo!"
I run a Win32 PPM repository for perl 5.6.x and 5.8.x -- I take requests (README).
** The third rule of perl club is a statement of fact: pod is sexy.
