# Perl::Critic::Policy::Modules::RequireNoMatchVarsWithUseEnglish(3pm)

"use English" must be passed a "-no\_match\_vars" argument.

## 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.
