There is a section in SICP about streams (

Neat-o.  I gave away my copy of that book 19 years ago when I finished with
the course.  I don't remember a thing about that book other than that it was
about Scheme.  To me, the course was learn-Scheme-to-get-an-A, but I always
thought the professors were trying to get at something more profound, I just
didn't care.  Get my A and get out of there.  Now that I'm older, I bet a
reread of the text would probably be more meaningful.  Thanks for the link.

 

For other erlang related code, there is an implementation in user
contribution of trapexit, and I wrote a very simple one too
http://khigia.wordpress.com/2007/05/07/44/ (the end contains few links which
could interest you).



That's a pretty good link, too.  For the lazy among you, I think the
Trapexit link being referred to is
http://forum.trapexit.org/viewtopic.php?t=6591.

Another *completely different* way to represent lazy lists is as processes

 

That's the way I probably would do it in real life Erlang.  (So if you
stumble across this thread and thought to copy my way, consider Joe's
first.)  I was going for more the brain-bending exercise of doing this
functionally.  The catch with a process is that it does not get
automatically garbage collected: would have to kill it manually.

 

Thanks.

 

Cheers,

 

David
