i phrased that poorly. the insight i meant to talk about was that the two
can be made effectively equivalent, through rewriting the conditional as
appropriate; the one exception would be when you don't want the loop to
run at all, in which case no amount of rewriting the conditional will make
a postcondition loop work for you - but if *that's* the case, most likely
you can just remove the loop entirely.
