Comment(by robertwb):
For immutable objects, like Parents, the default __hash__ could store the
value used the first time it is computed. This doesn't solve the problem
of
{{{
sage: bla = PolynomialRing(ZZ,"x")
sage: hash(bla['t'])
-1733828288
sage: bla.rename("toto")
sage: hash(bla['t'])
-1924319844
}}}
