=head1 NAME

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

=head1 SYNOPSIS

    use English;
    ...
    if ($ERRNO =~ /denied/) { ... }

=head1 DESCRIPTION

You should I<not> use this module in programs intended to be portable
among Perl versions, programs that must perform regular expression
matching operations efficiently, or libraries intended for use with
such programs.  In a sense, this module is deprecated.  The reasons
for this have to do with implementation details of the Perl
interpreter which are too thorny to go into here.  Perhaps someday
they will be fixed to make "C<use English>" more practical.

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 B<awk> version, both long
and short English alternatives are provided.  For example, 
the C<$/> variable can be referred to either $RS or 
$INPUT_RECORD_SEPARATOR if you are using the English module.

See L<perlvar> for a complete list of these.
