------------------------------------------------------+---------------------
Polyhedra (objects of class Polyhedron) cannot be dumped or saved:
{{{
sage: polytopes.dodecahedron(QQ).dumps()
---------------------------------------------------------------------------
PicklingError Traceback (most recent call
last)
/home/terhorst/<ipython console> in <module>()
/opt/sage/local/lib/python2.6/site-packages/sage/structure/sage_object.so
in sage.structure.sage_object.SageObject.dumps
(sage/structure/sage_object.c:2108)()
PicklingError: Can't pickle <type 'function'>: attribute lookup
__builtin__.function failed
}}}
As a workaround, I pickle a hash of the rays, vertices, and lines defining
the polyhedron.
