The idea is that you will be able to mark your Nullable/Variant 
type as @nodiscard, and the compiler will warn you if you forget 
to check it.

Marking the type as @nodiscard also means you will not have to 
annotate the individual functions, so in practice the number of 
@s needed should be fairly small.
