Well coordinate access is only a part of what makes a point a hard-sell.
There are hundreds of years of geometry and many API's to contend with
as well.  I kind of think (hope) that if the scope is kept extremely
limited then it is possible to come up with generic point concepts, and
maybe a reference implementation, that would make everybody happy.  Is
the boost wiki where these ideas could be fleshed out?
