--- Comment #5 from Ivan Lazaric <ivan.lazaric.gcc at gmail dot com> ---
Turns out I didn't understand `extract-ref`, and was missing `object_of()`
Fixed and simplified example exhibiting link failure:
```cpp
#include <meta>
template<typename>
struct storage {
static inline int value = 2;
};
int main() {
return extract<int&>(object_of(^^storage<int>::value));
}
```
