Perl::Critic::Policy::Modules::RequireNoMatchVarsWithUseUseriContributed Perl DoPerl::Critic::Policy::Modules::RequireNoMatchVarsWithUseEnglish(3)

NAME

       Perl::Critic::Policy::Modules::RequireNoMatchVarsWithUseEnglish - "use English" must be passed a "-no_match_vars" argument.

AFFILIATION

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

DESCRIPTION

       Due to unfortunate history, if you use the English module but don't pass in a "-no_match_vars" argument, all regular expressions in the
       entire program, not merely the module in question, suffer a significant performance penalty, even if you only import a subset of the
       variables.

	   use English; 			     # not ok
	   use English '-no_match_vars';	     # ok
	   use English qw< $ERRNO -no_match_vars >;  # ok
	   use English qw($OS_ERROR);		     # not ok

       In the last example above, while the match variables aren't loaded into your namespace, they are still created in the "English" namespace
       and you still pay the cost.

CONFIGURATION

       This Policy is not configurable except for the standard options.
