No. list? is not broken. Every list is a seq, but not
every seq is a list.
Consider: (cons 0 (iterate inc 1))
This is no list! It's a sequence. Why should list?

Hello,
Undoubtedly it is not the best solution, but all I do is export a variable
called CLASSPATH
pointing to whichever directories I want to require or load.

CLASSPATH=/home/user/aaa:/home/user/bbb:$CLASSPATH
export CLASSPATH

The only gotcha so far

If Rich wants to keep his stuff there because it meets his needs and
he is fully aware of what they do and how they do it then all of this

I think you just forgot to return the value itself. This seems to
work:
(defn produce [value predicate generator]
(when (predicate value)
(let [result (generator value)]
(cons result (lazy-seq (produce result predicate
generator)
)
And I would use "quot" instead of "u

But the Clojure website is clojure.org. NOT clojure.wikispaces.org or

I think, it's the latter. Here my try on an explanation:
