I already answered that up-thread: it will be dead code, and thus will
likely do the wrong thing if it ever runs.
I also suggested what to do instead: add assertions that express what
we believe should never happen. Stefan says doing that is unlikely to
be justified by the dangers, but if we think so, then we shouldn't be
afraid of the problem in the first place. If we are, then adding
assertions is the way to go.
