From the doc of `Polyhedron.delete` (which is a immutable/hashable
object):
{{{
Delete this polyhedron.
This speeds up creation of new polyhedra by reusing
objects. After recycling a polyhedron object, it is not in a
consistent state any more and neither the polyhedron nor its
H/V-representation objects may be used any more.
}}}
This really shouldn't be exposed at user level:
{{{
sage: p = polytopes.cube()
sage: p.delete()
sage: p
/home/ncohen/.Sage/local/lib/python2.7/site-
packages/sage/repl/rich_output/display_manager.py:570: RichReprWarning:
