<pre wrap="">Actually, your negative abstract turns out to be for a quite positive article. List are like iterators, that's the essence, and as long as you are iterating, it's fine to use []. The prominence of singly linked lists in Haskell has tought me to write my data processing programs in a streaming style.</pre>

<b>Yes.</b> I've been teaching not just "data processing" - after
all almost everything we program is "data processing", no?... but
such concrete stuff as physics simulation (diff. eqs.), some other
numerics (asymptotic expansions, etc.) signal processing (including
sound generation), and I liked to present several examples in a <b>dataflow
style</b> with plenty of co-recursive contraptions. Haskell lazy
lists were natural, concise, and easy to manipulate. We enjoyed it,
wrong or not.<br>

Nothing is perfect, not only mister Nobody; calling ANY approach to
programming "wrong" is sectarian. A professional coder working on a
concrete project may say bad words about anything he wishes, but for
a teacher this is a pedagogical sin, and inefficient programs can be
more inspiring than some "correct" doctrines.<br>
