Given the rules for resolving ambiguous else there is _always_ exactly one
way this can be parsed, even if it is not a full if-then-else tree.
Otherwise you would not be able to write it in the first place.  After
all, this is only a warning, and will also protect you against future
changes that may make it ambiguous again.
