The documentation does not explicitly mention which of both approaches is recommended to implement the free function of the graph concepts for a custom graph. Usually the graph will be in its own namespace.
Should the free functions be declared in the boost namespace or in the same namespace as the graph?
In the same namespace as the graph.
Maybe that should be stated explicitly somewhere.
This also would determine if BGL functions should be called qualified or unqualified outside of namespace boost.
They should be called unqualified; I try to make sure that examples do that so that they will work on user-defined graph types.
The LEDA example [1] does exactly the opposite. Probably that would be a good start.
