4.3.12 Getting Component Associated with the Object

   4.3.12.1 get_component

   Object get_component ();

   If the target object reference is itself a component reference (i.e., it denotes the component itself), the get_component operation returns the same reference (or another equivalent reference). If the target object reference is a facet reference the get_component operation returns an object reference for the component. If the target reference is neither a component reference nor a provided reference, get_component returns a nil reference.
