Bruno,

I have understood your idea that way.

Actually, I have thought it would be range:

for_each(points_range(p), do_something_with_polygon_points);
for_each(segments_range(p), do_something_with_polygon_segments);

though I'm more inclinde to view terminology. Boost.GIL uses image_view
and describes it as "lightweight object that interprets memory"

A view concept is well-settled in C++ world and also well integrates
with iterators -
"as a looking glass through which the objects can be looked at"
