Of course, bg::model::ring is adapted to Boost.Range concept and also
has operator[]. If you had your own Ring type you could use any methods
defined in it. E.g. in my eariler email if you adapted
std::vector<Eigen::Vector2d> to a Ring concept you could of still call
any method and operator defined in std::vector.

My point was that maybe you could avoid doing it manually. I don't know
what you're planning to do exactly but since you're ignoring the
interior of a Polygon when calculating distance then maybe a Linestring
would be a better representation? You could e.g. use
