NAME

6       Perl::Critic::Policy::Variables::ProhibitMatchVars - Avoid "$`", "$&",
7       "$'" and their English equivalents.
8

AFFILIATION

10       This Policy is part of the core Perl::Critic distribution.
11

DESCRIPTION

13       Using the "match variables" "$`", $&, and/or "$'" can significantly
14       degrade the performance of a program.  This policy forbids using them
15       or their English equivalents.  See perldoc English or PBP page 82 for
16       more information.
17
18       It used to forbid plain "use English;" because it ends up causing the
19       performance side-effects of the match variables.  However, the message
20       emitted for that situation was not at all clear and there is now
21       Perl::Critic::Policy::Modules::RequireNoMatchVarsWithUseEnglish, which
22       addresses this situation directly.
23

CONFIGURATION

25       This Policy is not configurable except for the standard options.
