In fact, this capacity is useful (some might say "essential") for *all*
dynamically dispatched functions, not just those named AUTOLOAD. One ought
to be able to write:

	sub B::m
	{
		my ($self) = @_;
		if (some_condition())
		{
			return $self->NEXT::m();
		}
	}

where NEXT is analogous to SUPER, but resumes the current dispatch
search, rather than initiating a new dispatch.

BTW, the next version of Class::Multimethods will provide this type of 
redispatch.
