Spécialisation et sous-typage : thème et variations
Class specialization is the most original feature of object orientation, but identifying it to subtyping leads to the well known covariance-contravariance controversy. Type safety requires contravariance while specialization needs covariance. This paper aims to precisely analyse this problem, to show how irreductible it is and the need for type errors. We show that many alternatives as multiple...
