Ah, now I understand. That code in Config.pm isn't part of std perl, its something that ActiveState must have added. Yes, it's definitely something you'd have to raise with them rather than via perlbug.

NB - you can use perlbug to report a bug in something like CGI.pm; anything that's bundled in the core becomes our responsibility (although we're likely to pass the report straight onto the author for fixing ;-)
