Perl::CriticPerl::CritUserPContributedlPerlRDocumentationVarsWithUseEnglish(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.
