       Using the "match variables" "$`", $&, and/or "$'" can significantly degrade the performance of a program.
       This policy forbids using them or their English equivalents.  See perldocEnglish or PBP page 82 for more
       information.

       It used to forbid plain "use English;" because it ends up causing the performance side-effects of the
       match variables.  However, the message emitted for that situation was not at all clear and there is now
       Perl::Critic::Policy::Modules::RequireNoMatchVarsWithUseEnglish, which addresses this situation directly.

       Perl::Critic::Policy::Variables::ProhibitMatchVars - Avoid "$`", "$&", "$'" and their English
       equivalents.
