Zusammenfassung:	Abstract: "Polymorphism[CW885] is defined as the potential for a variable or function parameter to have a value of one type at one point in time, and a value of a different type at another. In this paper, we propose an extension to the C++ language that offers the polymorphism flexibility of multiple inheritance without its software engineering disadvantages. Rather than relying on inheritance, our extension allows polymorphism to be achieved by explicitly defining a signature (public class interface) required at a usage or call site. Any object whose class conforms to the designated signature can be bound to a variable or formal parameter at that site When a member function is invoked on a pointer or reference with a signature as its declared type, the corresponding member function of the referenced object's actual class is invoked. The class's [sic] member functions that correspond to the signature's member functions can be virtual, inline, neither or both.
