Yeah, perhaps trying to make the generic graph search apply to your
case is not the right thing to do, and that is OK. For example, you
can't write every sequential container algorithm using std::transform :)

The graph_search does apply well to standard depth-first,
breadth-first, and some other common algorithms like dijkstra's and
