Also, if you want nested iteration, use `for*'.

The for form iterates by drawing an element from each sequence; if any
sequence is empty, then the iteration stops. So this:
(for ([i (in-range 2 4)]
[j (in-range 1 2)])
(printf "i = ~s j = ~s\n" i j))
produces
i = 2 j = 1
at which point, the j sequence is now empty, so the entire i
2 matches
