One of Java's most prominent features is its type system. While its strict typing is normally a useful aid in writing consistent programs, it can also lead to verbosity. This is especially the case when processing similar types that represent the same or similar data, something that is common in DTO layers, or when versioning data types, two problems that are also current at the Norwegian tax authority (Skatteetaten). This presentation showcases how the introduction of structural types avoids boilerplate in the Norwegian taxation process, without loosing any type safety.
