[Boost-users] [BGL] Mixing bundled properties and property lists

Hi,
consider the following (excerpt from a) class wrapper around an  
adjacency_list:

using namespace boost;

template <typename VertexProperty = no_property>
class MyGraphWrapper {
private:
     typedef adjacency_list<vecS, listS, bidirectionalS,  
property<vertex_index_t, int, VertexProperty> > GraphImpl;
// ...
};

I want to store some property (in this case, a vertex index) inside  
the graph implementation, but at the same time I want to allow the  
client to specify further properties via the template parameter. May  
the client use the bundled property mechanism, e.g.

struct Label { std::string lab; };
MyGraphWrapper<Label> g;

My test compiled and it seems to run fine. Is it really possible/safe  
to mix bundle properties with property lists in this way? Or, is  
there a way to avoid property lists?
