Hi,

I have a graph implementation where
        get(tag, graph, out_edge_iterator)
is much more efficient than
        get(tag, graph, edge_descriptor)
which is probably not an usual case.

Would it make sense for BGL to provide a default implementation of the
former that dereferences the iterator and calls the latter? Graphs for
which the former is more efficient could then specialize this function
template.

Cheers,
Shaun
