Featherweight Java with multi-methods
Lorenzo Bettini, Sara Capecchi, Betti Venneri · 2007
Multi-methods (collections of overloaded methods associated to the same message, whose selection takes place dynamically instead of statically as in standard overloading) are a useful mechanism since they unleash the power of dynamic binding in object-oriented languages, so enhancing re-usability and separation of responsibilities. However, many mainstream languages, such as, e.g., Java, do not provide it, resorting to only static overloading.
