Heh, okay, I'll stick the casting method in Gst::Object (yeah, I realize
this breaks the GStreamer semantics of associating casting with the
interface, but it's more "perlish" this way... not to mention
implementable :).  Then glib can complain about prerequisite errors... and
if necessary, I can always add additional, more friendly error handling
later.
