Someone, please enlighten me!
Why is this clearer?
(defn foo
[a]
(let [b f1
c (comp f2 b)
d (comp f3 c)
e (comp f4 d)
g (comp f5 c)
h (comp f5 f2 e)]
(->> (iterate #(f7 (d %) (b %)) a)
(filter #(or (f6? (b %)) (<= (g %) (h %))))
first
e)))
It is more verbose than the loop. It generates 7 additional classes.
Per iteration step it calls b 5 times and c 3 times. Depending on b
and c maybe memoize should be considered, too. Why the first of the
resulting sequence, not the second? (<- The point here is: In which
way is defining a seq of uninteresting values to obtain a single one
cleaner than a loop which just returns that desired value? Maybe this
is really a fixpoint iteration?)
Sincerely
Meikel
