   ABSTRACT     = {Context. Features and styles inspired by functional 
      programming have grown in popularity in the world of object-oriented 
      programming. Immutability is a core concept of functional 
      programming, which brings advantages to software development. 
      However, introducing immutability in object-oriented programming 
      presents some challenges. Problem. One of these challenges is method 
      overriding. When inheriting non-destructive mutators (methods used on 
      immutable objects which return a new object instead of modifying the 
      receiver), a naive approach generates code duplication and has 
      scalability issues. Contribution. We analyse an example of this 
      overriding problem and propose a solution in a new design pattern 
      based on the factory method pattern. We also discuss the advantages 
      and limitations of this pattern, as well as implementations in 
      Clojure, Java, and Kotlin. We also identify and discuss the language 
      features that mostly affect the implementation of this pattern. 
      Conclusion. Our proposed design pattern helps mitigate some of the 
      code duplication and scalability problems of a naive approach. 
      However, the inclusion of a functional updating language feature is 
      required to completely remove the scalability issues.}
