I disagree. The question was not "This isn't working; what am I doing wrong?" it was "I've found a bug; how do I alert the maintainers?" Posting code is not appropriate in such a case. Of course, it could have been an XY Problem, but jumping to the conclusion that it was is not justified.

I disagree, too. To paraphrase what someone else wrote, "whenever anyone claims a Perl bug, the first thing I suspect is a hardware issue (probably a loose nut behind the keyboard)". Now, this may not be the case, but if the one reporting the alleged bug were a renown Perl hacker, it would be easier for me to believe it. When one is renown for not being a Perl hacker at all, let alone anything above the bare newbie, I would expect him or her to post some evidence and/or to investigate whether the "bug" is actually a bug.

So I am speaking out of prejudice, but hey, an informed one.
