Comment:

 The specialization proposed by the reporter is somewhat interesting since
 it only applies to directed graphs. Using the suggested specialization
 with an undirected graph will cause each edge to be given twice. It may be
 worth considering a !DirectedGraph concept that embodies this property of
 the out_edges() function. Conversely, an !UndirectedGraph concept may
 provide a different guarantee.

 However, the proposed solution - as given - won't work.
