 The public functions `instanceOf`, `subclassOf` and `includes` have been replaced by `Object.isInstanceOf`, `Object.static.isSubclassOf` and `Object.static.includes`.

     instanceOf(MyClass, obj)
     subclassOf(Object, aClass)

-The previous code will throw an error if `obj` is not an object, or if `aClass` is not a class (since they will not implement `isInstanceOf`, `isSubclassOf` or `includes`).
-If you are unsure of wether `obj` and `aClass` are an object or a class, you can use the methods in `Object`. They are prepared to work with random types, not just classes and instances:
