I think interfaces in Julia might go something like interface AnimalActions function walk(x::Animal) end function call(x::Animal, y::Animal) end function eat(x::Animal, z::Food) end end struct Dog <: Animal name::String end AnimalActions.walk(x::Dog) = true AnimalActions.call(x::Dog, y::Animal) = true AnimalActions.eat(x::Dog, z::Food) = true setinterface Dog AnimalActions end and then I guess using it like using AnimalActions d = Dog("rufus") walk(d)
