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,
the $/ variable can be referred to either $RS or
$INPUT_RECORD_SEPARATOR if you are using the English module.
See the perlvar manpage for a complete list of these.
This module provokes sizeable inefficiencies for regular expressions, due to unfortunate implementation details. If performance matters, consider avoiding English.
