Hi!

Why does the >> Operator not work using the Circual Kernel and
Line_Arc_2?

This is my code:
[...]
#include <CGAL/Exact_circular_kernel_2.h>

#include <CGAL/Arr_circular_line_arc_traits.h>

#include <CGAL/Arrangement_2.h>
#include <CGAL/Arr_naive_point_location.h>

typedef CGAL::Exact_circular_kernel_2                   Circular_k;

typedef Circular_k::Circular_arc_point_2                Point_2;
typedef Circular_k::Circle_2                            Circle_2;
typedef Circular_k::Circular_arc_2                      Circular_arc_2;
typedef Circular_k::Line_arc_2                          Line_arc_2;
[...]

  std::ifstream iEdgesFile("data/edges_tmp",std::ios::in);
  LineContainer lines;
  if (!iEdgesFile) {
    std::cout << "EdgesFile not found" << std::endl;
    return 1;
  }
  std::cout <<"Reading file..." << std::endl ;
  Line_arc_2 l;
  while ( iEdgesFile >> l ) {
    std::cout << "XY: " << l;
    //lines.push_back (l);
  }

This is the compile error:

Please help!
