And there, folks, you have one of the eternal dilemmas. The correct
decision depends on myriad factors; if you're writing code to go into
the documentation as an example, you want it to be able to handle
idiots hacking on it - but on the other hand, that same situation
demands simplicity, which is why a lot of examples omit huge slabs of
error checking.
