@interface ParametricNullness
Marks a "top-level" type-variable usage as (a) a Kotlin platform type when the type argument is
non-nullable and (b) nullable when the type argument is nullable. This is the closest we can get
to "non-nullable when non-nullable; nullable when nullable" (like the Android
NullFromTypeParam
). We use this to "undo" ElementTypesAreNonnullByDefault
.
