I know that an argument passed to a `ref int i` parameter is 
implemented with a pointer. And you would expect dip1000 to apply 
there as well, but the underlying type is still `int`, and scope 
only works on pointers.

Don't get me wrong, I rather see this work with value types as 
well, but this is how it currently works.
