       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 aawwkk 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.
