If your proposal handles some cases just as well as Matthias' proposal, it's no coincidence: those proposals have crucial elements in common. However, the elements those two proposals have in common are the same ones that raised the strongest objections from Robert, so we're trying to examine a less intrusive design for now.
Perhaps Robert can state for himself whether he considers http://lists.boost.org/Archives/boost/2005/11/97058.php unacceptable, and why. It is a very localized change. (Contiguous sequences with non-pointer iterators such as std::vector and std::string would also need to be touched slightly by manually inlining save_collection in their respective save overloads, but this is also minor; or alternatively, we can define boost::pbegin and use that in save_collection.)
