[gardening] Make code pass "perlcritic" review: Avoid subroutine prototypes.

> "perlcritic" is a Perl source code analyzer.  It is the executable front-end
> to the Perl::Critic engine, which attempts to identify awkward, hard to read,
> error-prone, or unconventional constructs in your code.  Most of the rules are
> based on Damian Conway's book Perl Best Practices.
