Correction:I _rarely_ find the need to copy other objects for _generic_ (er, templated) types (iterators being the exception I mentioned).
But obviously copying is essential for many concrete classes, e.g. vector. And I have never had the need for copying a vector to be "cheap" in any sense... in fact, I feel it _should_ be expensive, because of what it's doing. So it works out perfectly.
