FWIW, we didn't cover as_sequence in the book because we really couldn't come up with a use case that justified the non-uniformity in generic programs. If the type you pass happens to be a sequence already it gets treated differently :(.
I don't quite understand your negative reaction on difference. A lot of things are different :) If you couldn't find a good use case for generic programs, may be we could try find something interesting for "real" (I mean not generic) programs?
A solution looking for a problem? The one case we've seen in real designs is in boost::variant, and in that case I agree with Peter Dimov that the genericity breakage is unacceptable. http://lists.boost.org/MailArchives/boost/msg55143.php -- Dave Abrahams Boost Consulting http://www.boost-consulting.com
