> We introduce Higher Order Messaging, a higher order programming mechanism for dynamic object-oriented languages. Higher Order Messages allow user-defined message dispatch mechanism to be expressed using an optimally compact syntax that is a natural extension of plain messaging and also have a simple conceptual model. They can be implemented without extending the base language and operate through language bridges.
