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