However, I think it's important to note that they implement the very noisy
behavior of warning for all implicit fall-through. We could make our warning
much more useful by being silent for empty case statements, and in light of
other warnings starting with -Wswitch, I would recommend we name the warning
-Wswitch-fall-through or something similar. If we want to have an additional
warning that warns for all fall-through, as clang does, we could also add
-Wswitch-empty-fall-through.
