Well, what I meant was that if `super-curry' were later added, we'd support _both_ -- they could share 99% of the implementation (like rcurry and curry did [before I took out rcurry :-]). Presumably in that case, `ordinary' uses of curry would continue to use the "old" `curry' tag. -Miles -- .Numeric stability is probably not all that important when you're guessing.
