10English - use nice English (or awk) names for ugly punctuation variables
11
12=head1 SYNOPSIS
13
14 use English;
15 use English qw( -no_match_vars ) ; # Avoids regex performance penalty
16 # in perl 5.16 and earlier
17 ...
18 if ($ERRNO =~ /denied/) { ... }
19
20=head1 DESCRIPTION
21
22This module provides aliases for the built-in variables whose
23names no one seems to like to read. Variables with side-effects
24which get triggered just by accessing them (like $0) will still
25be affected.
26
27For those variables that have an B<awk> version, both long
28and short English alternatives are provided. For example,
29the C<$/> variable can be referred to either $RS or
30$INPUT_RECORD_SEPARATOR if you are using the English module.
31
32See L<perlvar> for a complete list of these.
33
34=head1 PERFORMANCE
35
36NOTE: This was fixed in perl 5.20. Mentioning these three variables no
37longer makes a speed difference. This section still applies if your code
38is to run on perl 5.18 or earlier.
39
40This module can provoke sizeable inefficiencies for regular expressions,
41due to unfortunate implementation details. If performance matters in
42your application and you don't need $PREMATCH, $MATCH, or $POSTMATCH,
43try doing
44
45 use English qw( -no_match_vars ) ;
46
47. B<It is especially important to do this in modules to avoid penalizing
48all applications which use them.>
