This Policy is part of the core Perl::Critic distribution.
Due to unfortunate history,
if you use the English module but don't pass in a
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.
This Policy is not configurable except for the standard options.
