Oops, an unexpected glitch from the master :-)
The last one won't exchange z and y, not generally. Since I'm a
righthanded-z_is_up-guy too, I usually use the matrix stuff to exchange y and z
for models made by other people:

#include "transforms.inc"
#declare Swap_yz_trans = transform{ Shear_Trans(x, z, y) };

#declare RightHandedObject = object{
   LeftHandedObject transform Swap_yz_trans };

hope that helps
