It is, however, a deprecated usage that consistently confuses people,
exactly as it has done here.

This motivates me to tackle the TODO item to get rid of the "iff"s.

So the job only has to be done once, what replacement will people be
happy with? Personally, I think plain "if" would be just fine, except
perhaps to the tediously literal-minded. Failing that, "only if".
As a last resort, "if and only if" (yuck).
