Good style for Perl includes using the strict and warnings pragmas, and
preferring lexical file handles over bareword file handles. Using
lexical file handles necessitates being explicit when $_ is printed, so
that Perl does not get confused and instead print the glob ref.
The benefit of this modernization is that a formerly obscured bug is now
visible, which will be fixed in a followup patch.
