Do you find it easy to use? Perhaps I just haven't s studied it in sufficient detail, but I don't. Moreover, I think that's. our informal project policy has tended toward, "use this only if there's no other way." I'll admit never having thought about rewriting it, or if there is a better algorithm, but I think this is certainly an area in which potential improvements should be considered.
