   ABSTRACT     = {\textbf{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. \textbf{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. \textbf{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. \textbf{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.}
