 // contains a non-nullable pointer, then this value is used as the discriminator.

+// item is represented as just a pointer and not wrapped in a struct.
 // Unfortunately (for these test cases) the content of the non-discriminant fields
 // in the null-case is not defined. So we just read the discriminator field in
 // this case (by casting the value to a memory-equivalent struct).
