=head1 NAME
|
|
|
|
English - use nice English (or awk) names for ugly punctuation variables
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
use English;
|
|
...
|
|
if ($ERRNO =~ /denied/) { ... }
|

|
=head1 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 $0) will still
|
|
be affected.
|
|
|
|
For those variables that have an B<awk> version, both long
|
|
and short English alternatives are provided. For example,
|
|
the C<$/> 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.
|
|
|
|
=head1 BUGS
|
|
|
|
This module provokes sizeable inefficiencies for regular expressions,
|
|
due to unfortunate implementation details. If performance matters,
|
|
consider avoiding English.
