Re: [boost] [type traits] add a set of templatesto propagate constetc from one type to another?

Note that John wrote about making To have the same cv-qualification as From, above. Hence, he called it "copy_cv." Your example, which is perhaps what John meant, is to make sure that To has at least as much cv-qualification as From, without removing any extra To already had. That suggests "augment" or "append."

I had intended "copy_cv" to mean: "Make To have the same qualifiers as From". At least intuitively that's what it means to me :-) I hadn't thought about the other form, I guess I'm hoping we don't need both! John.
