There is also a similar problem with the function read_wkt
    MultiPolygon mp;
    boost::geometry::read_wkt(s, mp);   
line52 of multi/io/wkt/read.hpp l52  contains "geometry.back()" while i don't have a container ; a few lines above there is a line with traits::resize<MultiGeometry>::apply(geometry, ...) which suggests that geometry is not necessarly a container.

Hi Renaud,

Looks like the library is using this ring as a container while the Ring concept specifies that Range requirements are supposed to suffice. Either we can rewrite this algorithm in such a way that it only uses the capabilities of a Range, or we need to revise the Polygon and/or Ring concepts.

Barend, any thought on this?
