NAME

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

SYNOPSIS

	   use English qw( -no_match_vars ) ;  # Avoids regex performance penalty
	   use English;
	   ...
	   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

       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.
