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