Even a single object gets you into the "all I wanted was a banana territory. " I have a gorilla class and a banana method on the class, can I ever use banana without the gorilla? No. The simple act of having a class screws it all up. Make the banana a pure function, or one that is defined in terms of a polymorphic parameter that it mutates. func banana(x: animal){...} banana(gorilla); The way to do it via OOP is base class methods and importing the method to all children via inheritance which is just bad and universally reviled among even practitioners of OOP. class Animal() { banana() } class Gorilla() : Animal { } Technically there are slight fair advantages and disadvantages to the OOP way when you don't account for inheritance and polymorphism but all that is gone once you do account for them.
