Comment (by SimonKing):
PS: With the idea exposed in the previous post, the following previously
failing examples would work:
{{{
age: M = ModularSymbols(6)
sage:
sage.modular.hecke.morphism.is_HeckeModuleMorphism_matrix(ModularSymbols(6).hecke_operator(7).matrix_form().hecke_module_morphism())
True
sage: loads(dumps(M)) == M
True
sage: A = J0(33)
sage: D = A.decomposition(); D
[
Simple abelian subvariety 11a(1,33) of dimension 1 of J0(33),
Simple abelian subvariety 11a(3,33) of dimension 1 of J0(33),
Simple abelian subvariety 33a(1,33) of dimension 1 of J0(33)
]
sage: loads(dumps(D))
[
Simple abelian subvariety 11a(1,33) of dimension 1 of J0(33),
Simple abelian subvariety 11a(3,33) of dimension 1 of J0(33),
Simple abelian subvariety 33a(1,33) of dimension 1 of J0(33)
]
}}}
