Very elegant, but sadly it blows the stack on larger collections. On my
system, the threshold is somewhere beetween 15.000 and 16.000 elements.
Something much less elegant (and slower in cases where your variant also
does the trick) is:
(defn fold-right [f s coll]
(reduce #(f %2 %1) s (reverse coll)))
