I prefer to have error defined right before we jump because it allows
reader to see explicitely set error condition instead of having to
verify if earlier code set it properly; it also forces you to set error
conditions on every error branch properly (if you forget while adding a
new one compiler will warn you about uninitialized variable), but I
won't insist.
