New description:
It seems impossible to save an object of the Parma Polyhedra Library's
`Variable` class and then load it.
{{{
sage: from sage.libs.ppl import Variable
sage: x = Variable(0)
sage: x.save(os.path.join(SAGE_TMP, 'pplvariable'))
---------------------------------------------------------------------------
AttributeError: 'sage.libs.ppl.Variable' object has no attribute 'save'
sage: save(x, os.path.join(SAGE_TMP, 'pplvariable'))
sage: load(os.path.join(SAGE_TMP, 'pplvariable.sobj'))
---------------------------------------------------------------------------
TypeError: __cinit__() takes exactly 1 positional argument (0 given)
