Going to 'perldoc perldata':
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.
Since Perl 5.8.1 was released in 2003, I think it's OK to not worry
about compatibility at this point.
