Done. Right now, we bail out in `getSectionRefsByNameOrIndex`, so I've also changed the code to use `cantFail`. I think it'd make sense for `getSectionRefsByNameOrIndex` to not bail out in this case (for one, because it also supports selecting sections by index), but that's a job for a different patch.
