Another benefit which I didn't see (though apologies if I glossed over it) is by moving properties into classes representing the domain, you avoid accidental comparison and assignment between completely unrelated items and the compiler can catch that.

Refactoring Rust: Primitive Obsession Fast smelly code is still smelly Thanks to their small, focused nature problems in Exercism tend to focus on language primitives. For example, a decimal might represent dollars. Changing one parameter leads to this horrible cascading effect and (if you're me) embarrasing refactoring meltdowns.
