> Could it be possible to define in the same patch functions
outdegree_sequence and indegree_sequence for DiGraphs ? :-)
Y-E-S, yes! :-)

The patch `trac_7564-degree-sequences.patch` implements the following
degree sequences:
1. `degree_sequence()` --- the degree sequence of a (di)graph. This is
implemented in the class `GenericGraph`.
1. `in_degree_sequence()` --- the indegree sequence of a digraph. This is
implemented in the class `DiGraph`.
1. `out_degree_sequence()` --- the outdegree sequence of a digraph, also
implemented in the class `DiGraph`.
I use the method names `in_degree_sequence()` and `out_degree_sequence()`
to be consistent with how the graph theory module names the indegree and
outdegree methods.
