Cast to and from the underlying type

It is recommended not to use casting operators, either explicit or implicit.

It might seem like a handy way to use the underlying primitive natively, but the goal of strong-typing primitives is to differentiate them from the underlying type.

Take, for instance, a Score type:

A cast operator, whether implicit or explicit would allow easy access to the Value, allowing things such as int n = _score + 10;. But what would be preferable is to be explicit and add a method that describes the operation, something like:
