interesection between segment and ring not defined

The intersection operation is not defined between a segment and a ring. It is however defined between a linestring and a ring. Is this a feature or bug? What am I missing here?

```
#include

namespace bg = boost::geometry;

int main()
{
using point = bg::model::point;
using segment = bg::model::segment;
using ring = bg::model::ring;

ring r = {{0,0},{0,1},{1,1}, {1,0},{0,0}};
segment s = {{-1,-1}, {2,2}};

std::vector points;
bg::intersection(s,r,points);

return 0;
}
```
results in
```
error: static_assert failed due to requirement 'boost::geometry::detail::static_assert_check>>::value' "Not or not yet implemented for this Geometry type."
```
