I thought I knew a little wacky Perl. Boy am I humbled now.
I found this lil beauty on the CPAN repository of JAPH's. It was the last entry.
I've run it through Deparse, that didn't help in the slightest.
I've run it through the Debugger, that only made things worse.

Will any monk much more enlightened than myself please help me understand?
