It seems to work. I had to do a little fix to your code though. In the
function_property_map you use 'value_type' which isn't defined and which
is, I believe :

typedef typename boost::property_traits<
                  function_property_map<Functor, Arg>
                 >::value_type
        value_type;

I also changed the functor type from 'Functor' to 'const Functor&'. It
seems to work. What was the rationale for copying it ?

My functor needs to have a pointer/reference to the graph to be able to
get the my_edge object from the edge_descriptor passed to the operator().

Thanks a lot!
