Passing raw arrays or lists across your system leads to duplicated logic, weak encapsulation, and hidden business rules. By reifying collections into dedicated, type-safe objects, you align your code with real-world concepts, centralize behavior, and reduce primitive obsession. Typed collection classes improve clarity, safety, and maintainability—often with negligible performance cost.
