- K::Ray_2 represents an infinite subspace of R².
- Circular_k::Line_arc_2 represents a finite segment of R², whose two 
endpoints are models of CircularKernel::CircularArcPoint_2.

Even with the linear CGAL kernel, you cannot convert a K::Ray_2 to a 
K::Segment_2.

If you want to convert a ray to a segment, you will need to clip the ray.
