Iso Disjoint Intersection Types

Abstract

On Bi and Oliveria’s paper “Typed First-Class Traits”, they design a new language named SEDEL. This language supports first-class traits, dynamic inheritance, dynamic dispatching and even abstract methods. However, there are still a few OO features that SEDEL cannot model, like binary methods. For addressing this issue, we introduce iso-recursive types in order to encode binary methods. The new language, SEDEL plus iso-recursive types, is called iso-disjoint intersection types!
