I'm not quite sure I understand the purpose of this structure. As far as I can tell, it's isomorphic to list (even under laziness) with some minor differences in performance characteristics (determining whether a cons cell is terminal requires evaluating the subsequent list to WHNF, whereas in your structure it follows from the constructor. But I think that's just a minor performance detail). On 11/25/2015 8:04 PM, Silvio Frischknecht wrote:
