I don't think you can label this as buggy code unless you can point to the
spec and say where it is disallowed. It is certainly something that looks
dangerous and is unlikely to be written by the average developer, but that
doesn't make it illegal. I lean towards the notion that when I say setXXX
that's the time the value must be saved because that's certainly more
intuitive and specific than "sometime later when the driver decides to."
