I forgot to mention that this approach, apart from potentially being
dangerous due to the ref-reuse prolem, has the obvious limitation that
applicatively equivalent keys will not match elements. I *must* have
$time to restore the value. I will be disappointed if I do

    $time2 = [ 100, 200 ];
	return $CAA->{$time2}; #undef

What I typically want for object keys is that they associate to the same
element if they pass (in Javaesque parlance) an isEqual test.
