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 5.16 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.
