Thanks Peter, Ian. I have modified my code to expand transitive relations and ask you to view it on stackoverflow via the original link (as posting code on newsgroups is an ugly hack).

My main reason for the post to c.l.p remains though; it seems like a *natural* use of the cmp= comparator function to sorted rather than using key= .
