Your code sample seems to suggest adding a fwd ctor and possibly a fwd operator= to the boost::geometry::model::ring class. Well, that would certainly be appreciated. However, instead of adding to the interface until it offers a full replication of the base container's interface, wouldn't it be simpler and more straight-forward to eliminate this hollow shell altogether? The existing ctor that takes a pair of iterators and merely forwards them to the base class actually illustrates my argument.

I am aware that I can always implement my own model of polygon and ring. At this point, there is no compelling reason for me to do so, the simple and basic default models are just fine. Yet I thought I might suggest a simplification to that default implementation. No offense!

Regards
