If a function has an interface you don't like, don't hack around it every time you call it and don't shut off the warning. Fix the function.

    use Scalar::Util ();
    sub reftype ($) {
        return '' if !defined $_[0];
        return Scalar::Util::reftype($_[0]);
    }

As for the "$Your::Global = 1" used only once problem, I hate that warning. I wrote up the your.pm module to work around it but its no less typing.
