I would have hoped perl would have thrown a warning about that, but since it doesn't (at least 5.8.8 and 5.10 don't), I will: from http://search.cpan.org/~rgarcia/perl-5.10.0/pod/perldata.pod#Version_Strings Note: Version Strings (v−strings) have been deprecated. They will be removed in some future release after Perl 5.8.1. The marginal benefits of v−strings were greatly outweighed by the potential for Surprise and Confusion. -- Chas.
