NAME
       English - use nice(1,2) English (or awk) names for ugly punctuation vari-
       ables

SYNOPSIS
           use English qw( -no_match_vars ) ;  # Avoids regex(3,7) performance penalty
           use English;
           ...
           if(3,n) ($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 trig-
       gered just by accessing them (like $0) will still be affected.

       For those variables that have an awk version(1,3,5), both long and short
       English alternatives are provided.  For example, the $/ variable can be
       referred to either $RS or $INPUT_RECORD_SEPARATOR if(3,n) you are using the
       English module.

       See perlvar for a complete list of these.

PERFORMANCE
       This module can provoke sizeable inefficiencies for regular expres-
       sions, due to unfortunate implementation details.  If performance mat-
       ters in(1,8) 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(1,8) modules to avoid penalizing
       all applications which use them.
