Primitive Obsession Problem. This is the Primitive Obsession code smell. Some implementations represent high-level design concepts with primitive types. The DieValue enum represents the value of a single Die. 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. Primitive Obsession is a code smell and type of anti-pattern where you are trying to use primitives for definable basic domain models. It’s an obsession of using primitives and for making the code better this code smell requires remediation efforts.

I have the impression that finally in some way, fighting primitive obsession (for instance transforming an array in a small object) drives to create data classes.I guess it is a bit subbtle, but I don't get it and to say the truth I prefer creating data classes than having a huge of arrays that make sens together and represent more concepts than arrays.I really would like to discuss it with you.
