I thought about that for a bit while working on the knngist patch, but
couldn't really see any useful application. In particular, I don't see
a way to shoehorn + and - in there as ordering operators. They don't
match the structure. The RANGE problem wants to add operators that are
somehow related to a btree's operators, but they're not related in the
way that knngist uses.
