You should use SRFI-41, as SRFI-40 is deprecated.<br><br><div class="gmail_quote">On Sat, Mar 5, 2011 at 6:31 PM, Mark Engelberg <span dir="ltr"><<a href="mailto:mark.engelberg@gmail.com">mark.engelberg@gmail.com</a>></span> wrote:<br> <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">I've had some email discussions about this with the Racket team in the<br> past, so here's a quick unofficial summary of what I've learned, while<br> you're waiting for a more official response:<br> <br> racket/stream is not really a "stream library" by the typical Scheme<br> definition of stream. It's really a library to manipulate Racket's<br> sequence abstraction with list-like functions. The naming is<br> misleading. The whole library is experimental and is likely to change<br> and you shouldn't really be using it anyway.<br> <br> Racket does not have a built-in stream library that integrates nicely<br> with its sequence abstraction and uses the same naming scheme as its<br> built-in list functions. The srfis 40 and 41 will serve your most<br> basic stream needs though (I think I've had better luck with srfi41).<br> <br> I get the impression that adding a complete, tightly-integrated stream<br> library to Racket is of interest to the developers, but not a high<br> priority because:<br> a) There are tons of things competing for their development time, and<br> something like a stream library is exactly the kind of thing that<br> could be easily written by a motivated user.<br> b) They believe that Lazy Racket can be used in many situations where<br> you'd want to use streams.<br> <div><div></div><div class="h5">_________________________________________________<br> For list-related administrative tasks:<br> <a href="http://lists.racket-lang.org/listinfo/users" target="_blank">http://lists.racket-lang.org/listinfo/users</a><br> </div></div></blockquote></div><br>
