Object.getPrototypeOf would not help me at all since it would not allow me to assign a *new* __proto__ to a function I just created, but I *am* mistaken, Function.create() would be sufficient in my cases.
There's still more flexibility in __proto__ to reassign __proto__, which Function.create and Object.getPrototypeOf would not provide.
