perldoc perlvar says:
The revision, version, and subversion of the Perl interpreter,
represented as a "version" object.
This variable first appeared in perl 5.6.0; earlier versions of perl
will see an undefined value. Before perl 5.10.0 $^V was represented
as a v-string.
I'm quite sure David isn't running on something older than 5.10.0.
