I want to use this to generically define interior edge-properties for reversed graphs, if the underlying graph has them as well. Currently this does not work, because I cannot access the underlying graph object.

For a reverse_graph's bundled properties operator[] simply dispatches to
the underlying graph's operator[].

reverse_graph has a public GraphRef m_g member attribute.
It should be private and a implementation detail. But it isn't.

But can you elaborate a bit on your use-case?
