Core.add(a, b) Trait-based dispatch A natural extension to the iterated dispatch above is to add a layer to method selection that allows to dispatch on sets of types which are independent from the sets interacts with the fields of an object. Instead of granting direct access to type fields, an extra layer of abstraction between the user and the code can be provided by overloading object.field.
