Comment(by brunellus):
Hi! I think this is not the case because the DiGraph object is not used in
the resulting tuple -- it is just a device to get all arcs. Maybe I don't
understand it correctly, but I assume that allow_multiedges is pickled one
level higher, in the SparseGraphBackend object.
{{{
sage: loads(dumps(Graph({0: [1]})))
Graph on 2 vertices
sage: loads(dumps(Graph({0: [1,1]})))
Multi-graph on 2 vertices
}}}
What do you think?
