perl::critic::policy::variables::prohibitmatchvars
Perl::Critic::Policy::Variables::ProhibitMatchVars(3pm) User Contributed Perl DocumentationPerl::Critic::Policy::Variables::ProhibitMatchVars(3pm) NAME
Perl::Critic::Policy::Variables::ProhibitMatchVars - Avoid "$`", "$&", "$'" and their English equivalents. AFFILIATION
This Policy is part of the core Perl::Critic distribution. DESCRIPTION
Using the "match variables" "$`", $&, and/or "$'" can significantly degrade the performance of a program. This policy forbids using them or their English equivalents. See perldoc English 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. CONFIGURATION
This Policy is not configurable except for the standard options. AUTHOR
