This series is about enums only afaics. Yet the rule is much wider, and iirc
we had agreed that for integer and pointer types the normal language
conversion to boolean meaning is fine as well. Not only do you not mention
this case in the entry, but it also continue to mean that effectively we
limit the rule to a very narrow case. Which continue to leave open the
question of whether the rule is worthwhile to accept in the first place.
