I don't think anyone is saying never implement an algorithm. There's a time and place. I've seen code bases where these algorithms had ten different implementations, some of the with subtle bugs, some of them with some performance issues. Your code will also need to be maintained down the line. There's more to software engineering than writing toposort. Obviously(?) my Boost proposal was made in jest. Anyways, maybe I'm a little bit jealous that you get to do this all the time ;) I just hope I'm not the one that has to maintain it down the road...
