course a useful point class will model both the coordinates and the point concept. To me a point should really support transform, scale, rotate, shear, and distance operations as free functions (maybe more).
I don't know how to handle the idea of a 'space' or a 'kernel'.

That paper uses syntax that is not yet part of _most_ C++ compilers, so I would like a proposed library to use the BCCL (http://www.boost.org/libs/concept_check ).
