Well, you can't really rely on _anything_ -- there is no way of testing
_only_ the feature you're trying to test.

But yes, I agree with you that adding the "return 0;" would be a nice
cleanup, not only to reduce "risks" but also just for style points.
See the one line you snipped from my message ;-)
