I also tend to abhor programs with more than one entry/exit
point, for they make their proof of correctness much harder
(or, if you're not into the more theoretical side of the
world, s/proof of correctness/auditing/).
Of course, with throw-away scripts, I don't have such worries,
but if the thing is a bit longer than a couple of pages, I try
to make it as strict as possible.
