I sometimes use this in combination with the -s switch.

use warnings;
say STDERR 'reticulating splines'
unless $::q;
In other words it's a way of me saying, yes, I really want the global var $q
in the main namespace.
(some people might argue I should use 'our' here. They might be right -
especially in the case where I use a command lone switch only once, in which
case warnings will ommit a warning)
