Thank you very much for the pointer. Indeed that's the bug that I encountered.

I installed a 5.8.8 distribution with perlbrew and can now reproduce the issue, which system Perl could not. Apparently my distribution patched this bug.

Is there a reason that your blog doesn't recommend Flavio's solution of using cloistered modifiers? It seems cleaner and more complete that what your detective work uncovered.
