Another way of looking at Clojure code is not a top down abstraction
first view, but as the building of a system from smaller parts. The best
example of this is clojure/core.clj . Sure it's bootstrap code so it can be

This is an old thread, and whatever problems you might be dealing with now,
they're probably not the same ones as when the thread was active. However,
I think that if parallel code uses the built-in Clojure random number

I'm trying to “internalize” loop/recur as being a functional construct.
I'm sure I'm not alone in this: I initially struggled with it, with my view
unduely influenced by its implementation, especially when multiple loop
heads are present. (It could be viewed as vulgar but necessary imperative
loop/recur is explicit tail recursion, and therefore will only work if the
recur is in the tail position, i.e. the last form evaluated.
For example, this function is tail recursive:
(defn sum [coll result]
(if (seq coll)
(sum (rest coll) (+ result (first coll)))
0))

Have you considered the similarity between loop-recur and sequence
operations?
IE, tail-recursion turns the call stack into a sequence of states. The
nice trick you can play in clojure is to reify this sequence as a lazy
sequence.

ODT files from OpenOffice/LibreOffice are just Zip files which contain a
