I love the cpan testers. I have fixed so many problems with my modules because of that project.

However, getting reports that certain 5.8 things don't work in 5.6 is less helpful... I considered that my problem though. When I asked, it was because I needed a way to instruct 5.6 testers to skip a module: testers.cpan vs perl 5.8.

The answer was to "use 5.008" at the top of the Makefile.PL. Although, the obvious work around was to use a code block thingy in my print statement (ie {$fh}).
