Along similar lines, I have this one-liner as ~/bin/pmv:
#! /bin/sh
perl -m$1 -le 'print '$1'->VERSION || die "No VERSION in '$1'\n"'

So do I. In fact I used to use $VERSION in my script, but changed to
->VERSION after some situation in which it worked and $VERSION didn't.
Sorry, I can't right now remember what that was.
