Certainly, but the point is that Perl 6 is going to make laziness possible and convenient, not that it will magically change unlazy algorithms to be such. I thought your comment was about Perl 6 more generally than the code in the OP, so my reply was intended to be more general as well. Sorry if there was any misunderstanding.

Update: Re: tye's reply: explanation understood, but I don't really have any answers to his further questions.
