The advantage of them is that they can be done by arithmetic without > a lookup table, and thus presumably faster. Can you list which case-insensitive procedures would be useful? Is < enough or are <= and > and >= and = useful for something as well? What about case-sensitive comparison procedures - is it enough to have the Unicode ones? ASCII ones would normally give the same results as the Unicode-aware ones, but are there some Unicode gotchas that would be avoided by the simple ASCII versions?
