Doug,
Although I was puzzled about the context, I loved reading your paper! So
it was a happy mistake as far as I'm concerned :-)
I found it fascinating to realize the equivalence between processes
connected by pipes and lazy lists with function composition. And I'll
definitely be adding that two-liner to my repertoire of cool examples
that I use when trying to explain the virtues of lazy functional
programming to others. The other one that I use is the fairly well-known
recursive Fibonacci generation: fibonacci = 1 : 1 : zipWith (+)
fibonacci (tail fibonacci).
By the way, for your Try It section, you might want to consider using
codepad.org <http://codepad.org>, "an online compiler/interpreter, and a
simple collaboration tool. It's a pastebin that executes code for you.
You paste your code, and codepad runs it and gives you a short URL you
can use to share it." For example, through something written here a few
days ago, I came across a fascinating generator of rational
approximations to pi written in Haskell, and the author used codepad.org
<http://codepad.org> to show both the code and the results. The code is
at http://codepad.org/C2IVTlCC and the explanation is at
https://www.quora.com/What-is-the-best-rational-approximation-of-pi-Let-best-be-the-difference-between-the-number-of-digits-used-to-represent-the-rational-and-the-number-of-accurate-digits-in-the-decimal-expansion/answer/Anders-Kaseorg
Understandably, the implementation of codepad.org <http://codepad.org>
is careful about setting resource limits, so it would be interesting to
see how well it handles your shell and C programs, both of which are
effectively fork-bombs.
