		133	Set the priority for all following handlers/hooks (unless overwritten

		135	earlier. The default priority is C<0>, and many built-in handlers are

		143	handlers are recognised generally depends on the type of object these
		144	handlers attach to).

		153	object/class are recognised.

		155	=back

		158
		159	Attach handlers for a specific object type (e.g. TRANSPORT) and
