Stuff with the Perl Foundation. A couple of patches in the Perl core. A few CPAN modules. That about sums it up.
HOP is a wonderful book. However, what's not wonderful about the book is the lack of strict. I just spent 3 hours trying to track down a problem when I remembered that the code didn't use strict. Two seconds later, I found my bug. Grr ...
While this error you've spotted is possibly a typo, that wasn't in Mark's original code, to me it highlights why use strict and warnings are such useful things to include in your programs.
Mark is not a fan of strictures for some bewildering reason. None of the program repair shop articles at Perl.com use strict either. I wonder stance his new book will take.
