There is a valid reason to use a "run-once" loop (though Dyson's code doesn't do it). It lets you use a shift register to remember a value between runs of the surrounding vi. If you have a bunch of such values you need to keep around, a single loop surrounding the relevant functions can be a little cleaner than a bunch of feedback nodes.
