/**
* This is an optional value type. It holds a `Result` and, if that code is ResultSuccess, it
* also holds a result of type `T`. If the code is an error code (not ResultSuccess), then trying
* to access the inner value with operator* is undefined behavior and will assert with Unwrap().
* Users of this class must be cognizant to check the status of the ResultVal with operator bool(),
* Code(), Succeeded() or Failed() prior to accessing the inner value.
*
* An example of how it could be used:
* \code
* ResultVal<int> Frobnicate(float strength) {
* if (strength < 0.f || strength > 1.0f) {
* // Can't frobnicate too weakly or too strongly
* return Result{ErrorModule::Common, 1};
* } else {
* // Frobnicated! Give caller a cookie
* return 42;
* }
* }
* \endcode
*
* \code
* auto frob_result = Frobnicate(0.75f);
* if (frob_result) {
* // Frobbed ok
* printf("My cookie is %d\n", *frob_result);

* printf("Guess I overdid it. :( Error code: %ux\n", frob_result.Code().raw);
