Script Preparation code:

	return (obj1 === obj2)
};

function versionedCheck(obj1, obj2) {
	if ((obj1 == null) && (obj2 == null)) return true;
	if ((obj1 != null) && (obj2 != null)) return (obj1._v_ === obj2._v_);
	return false;
};

function immutableOrVersionedCheck(obj1, obj2) {
	if ((obj1 == null) && (obj2 == null)) return true;
	if ((obj1 != null) && (obj2 != null)) {
		if (obj1._v_) return (obj1._v_ === obj2._v_);
		return (obj1 === obj2);
	}
    return false;
};

function optimisationKiller(f, obj1, obj2) {
  	isEqual = 42;
	isEqual = f(obj1, obj2);
	res = isEqual;
}

object1 = { _v_: 1 };
object2 = { _v_: 2 };
