		133	earlier. The default priority is C<0>, and many built-in handlers are
		134	registered at priority C<-1000>, so lower priorities should not be used
		135	unless you know what you are doing.

		139	Call the given code reference whenever the named event happens (event is
		140	something like C<instantiate>, C<apply>, C<use_skill> and so on, and which
		141	handlers are recognised generally depends on the type of object these
		142	handlers attach to).
