  I think it would come closer to OO if you could do something like:

class MySphere: specializes sphere
{
  virtual setCenter(Coords)
  {
    do_something_with(Coords);
  }
}

  Then you could have functions (or macros) which take 'sphere' type objects
and to which you could give wither true spheres or your MySphere and if
this function calls 'setCenter', the correct implementation will be called.
