I will be honest and confess that I can't get my head around it. Not
your fault though! :)
I think I have a basic understanding of
co-(recursion|induction|patterns) so, at a lay-person's level of
understanding, can I conceptually think of these things as streams
very similar to, for example, those processed by the Monadic Stream
Functions that Ivan Perez mentions in another email?
And then there is some additional analytical or performance
advantages, maybe especially in cases of infinite streams, achieved by
representing them in this manner?
I think I'll need to study up to really appreciate it but, at the very
least, I'm thankful for the link to your post as your reference to the
machines library led me off down an interesting research rabbit-hole.
