Take me over?
your - Perl pragma to declare use of other package's variables
use your qw($Foo::bar @Moo::you %This::that);
You should use variables from other packages with care, but as long as you're going to, it doesn't hurt to predeclare it.
Currently, if you use another package's variables and only use it once, Perl will throw a "variable used only once" warning. vars.pm won't allow you to declare other package's variables, and there are various hack to get around that. This package lets you declare "Yes, I am going to use someone else's variables!"
use Foo; use your qw($Foo::magic); print $Foo::magic;
