[boost] [serialization] implementing class_name_optional_type

Hi all, I'm working on the "YAML archives for Boost.Serialization" GSoC project and I've already implemented a working output archive. However, since YAML requires the class name to be always serialized, I had to implement the serialization of a new type called class_name_optional_type in basic_oarchive.cpp, which lets the archive decide if class names should always be written. It was discussed in the past [1], but never implemented, AFAIK. Cheers. PS: should I send the patch to this list or is it better to create a new ticket? 1 - http://lists.boost.org/boost-users/2006/06/20319.php
