Besides personally recommending *Perl* 5.12 I suggest also to carefully check killer apps, especially those with their own ecosystem and a bit less tightly sync'ed to CPAN. SpamAssassin for instance doesn't work yet with 5.12. And the SVN version which fixes 5.12 issues doesn't work as drop-in replacement. And I'm not sure about the current state of mod_perl2 which might affect your Apache2 toolchain. David Wheeler investigated some issues about 1 month ago [1]. So not sure this fits to your “Safety in numbers”, if you meant that… Kind regards, Steffen Footnotes: [1] http://aspn.activestate.com/ASPN/Mail/Message/perl-mod_perl/3839626 -- Steffen Schwigon <ss5@renormalist.net> Dresden Perl Mongers <http://dresden-pm.org/>Thread Previous | Thread Next
