You can also have use cases for both at the same time.
For example, a tree can be iterated by recursing on the left branches
and then looping on the right branches:
: (use Idx
(balance 'Idx (range 1 7))
(recur (Idx)
(tco (Idx)
(when Idx
(printsp (car Idx))
(recurse (cadr Idx))
(tc (cddr Idx)) ) ) ) )
4 2 1 3 6 5 7 -> NIL
