------------------------+-----------------------------
 It seems impossible to save an object of the Parma Polyhedra Library's
 `Variable` class.
 {{{
 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'
 }}}
