Streams, Rulers and Laziness

I discovered this course a while back and must say it is awesome. here&#x27;s the link for those who missed it in the article&#x27;s footer: <a href="http:&#x2F;&#x2F;www.seas.upenn.edu&#x2F;~cis194&#x2F;spring13&#x2F;" rel="nofollow">http:&#x2F;&#x2F;www.seas.upenn.edu&#x2F;~cis194&#x2F;spring13&#x2F;</a><p>For me personally, it is the best intro to haskell I could find, succint, to the point, and best of all are the assignments.

This is cool. I wonder what the performance is on large streams?<p>&gt;It doesn&#x27;t work because we haven&#x27;t defined interleaveStreams - which, for the sake of brevity, we will now refer to as iStr.<p>I much prefer `interleaveStreams` to `iStr`. I know Haskellers like to abbreviate things, but I think it just makes things harder to read for most people. What about using `interleave` and allowing the user to infer Streams from the function signature?
