But if we think about (?) and 'anti' like the set operators U (union)
and \ (difference), then 'nat ? anti evenNat' is like

nat U (nat \ even) = nat

Does really (?) behave like some kind of addition, or like some kind of
set union operator? Which is the behaviour in concrete FLP systems?

Greetings,

Juan
