That is an interesting idea.

Hi thanks all for your kind and informative replies. It would be great
to have at least some of the features headers-only (since CGAL uses
templates heavily anyway).
OK.

Oh only now I observe that the types are entirely different. I'll see

what I can do.
BTW it would be good if the polygons could use operator << and not
just push_back to add points -- it would make programming so much
easier, no?
polygon << Point_2(10,10) << Point_2(20,30) ... ;
