Examples

• Browse 2 set of coordinates at the same time:

  mln::box2d box1 = {{0,0}, {2,3}};
  mln::box2d box2 = {{1,1}, {3,4}};
  mln_foreach(auto [p1, p2], ranges::view::zip(box1, box2))
    std::cout << "[" << p1 << ", " << p2 << "]\n";
  

  Outputs:

  [(0,0), (1,1)]
  [(0,1), (1,2)]
  [(0,2), (1,3)]
  [(1,0), (2,1)]
  [(1,1), (2,2)]
  [(1,2), (2,3)]
