- * Given an object and a list of properties or

- * inherited from that object.
- *
- * TODO: make it work with an inheritance chain, e.g., if you want inherited
- * properties or methods from both Function and Object, where Function itself
- * overrides methods from Object. We don't want to see that it inherits a
- * "valueOf" method from Function and again on Object.
- *
- * @param the object to inherit from
- * @param "properties" or "methods"
- * @param a list of properties or methods overridden by this object
