Dynamic trait replacement is a programming language feature for changing the objects' behavior at runtime by replacing some of the objects' methods. In previous work on dynamic trait replacement for JAVA-like languages, the object's methods that may be replaced must correspond exactly to a named trait used in the object's class definition. In this paper we propose the notion of replaceable: a programming language feature that decouples trait replacement operation code and class declaration code, thus making it possible refactoring classes and/or performing unanticipated trait replacement operations without invalidating existing code.

Abstract
Dynamic trait replacement is a programming language feature for changing the objects' behavior at runtime by replacing some of the objects' methods. In previous work on dynamic trait replacement for JAVA-like languages, the object's methods that may be replaced must correspond exactly to a named trait used in the object's class definition. In this paper we propose the notion of replaceable: a programming language feature that decouples trait replacement operation code and class declaration code, thus making it possible refactoring classes and/or performing unanticipated trait replacement operations without invalidating existing code.
