And here I just thought that BrowserUK had made a mistake by applying the scalar context to the hash slice. I would have been quite happy if it had been been written as @h{@a,@b,@c,@d} = () since that is clear on maintaining the list/list context. It also assigns "nothing" to each hash which is correct. So I'd use it in the amended form for production code.
