@AaronBallman I should have also noted the current design also allows for
headers that deliberately don't provide complete types to reduce compile times
which I believe is fairly common practice.
E.g.
```
// some_data.h
struct SomeData {
int value;
};
// list_handle.h
// Forward declare to avoid needing to include `some_data.h`
struct SomeData;
struct ListHandle {
struct SomeData* __counted_by(count) items;
size_t count;
};
