I wonder whether perlcritic has sufficiently deep understanding of
Perl code that it could find these hazards. I already checked,
and found that there's no built-in filter for this (at least not
in the perlcritic version I have), but maybe we could write one?
The rules seem to be plug-in modules, so you can make your own
in principle.
