In fact I have one. It is based on 2-3 finger trees as described in a paper by Ralf Hinze. it is even better because it is a ordered sequence data type, rather than just a priority queue: all operations are constant time at both ends (max resp.min end). It is also quite memory efficient (last time I checked, it used about half the memory compared to data.Set). I can send you the sources (today, evening, can't access it at work).
