Thanks! It is very interesting for me to see TCO in such elaborated
examples. I usually approach such tasks with loops, with a rather
different mental model.
Concerning swap, we could for completeness mention that there is also
the built-in 'xchg' function:
: (let L (1 2 3 4 5 6 7)
(xchg (nth L 3) (nth L 5))
L )
-> (1 2 5 4 3 6 7)
