NAME
    English - use nice English (or awk) names for ugly punctuation variables

SYNOPSIS
        use English;
        use English qw( -no_match_vars ) ;  # Avoids regex performance
                                            # penalty in perl 5.18 and
                                            # earlier
        ...
        if ($ERRNO =~ /denied/) { ... }

DESCRIPTION
    This module provides aliases for the built-in variables whose names no
    one seems to like to read. Variables with side-effects which get
    triggered just by accessing them (like $0) will still be affected.

    For those variables that have an awk version, both long and short
    English alternatives are provided. For example, the $/ variable can be
    referred to either $RS or $INPUT_RECORD_SEPARATOR if you are using the
    English module.

    See perlvar for a complete list of these.

PERFORMANCE
    NOTE: This was fixed in perl 5.20. Mentioning these three variables no
    longer makes a speed difference. This section still applies if your code
    is to run on perl 5.18 or earlier.

    This module can provoke sizeable inefficiencies for regular expressions,
    due to unfortunate implementation details. If performance matters in
    your application and you don't need $PREMATCH, $MATCH, or $POSTMATCH,
    try doing

       use English qw( -no_match_vars ) ;

    . It is especially important to do this in modules to avoid penalizing
    all applications which use them.
