Thanks Andrey. I like your idea of moving the guidelines to a different section and separating out C++03 details. Along those lines, I added two sections to the documentation: one for general usage guidelines and and one for TR1 specific guidelines. I also add a section describing known differences between decltype-based boost::restult_of and TR1 and another short section for differences between decltype-based boost::result_of and C++11. I also incorporated your example using the Boost.TypeTraits library to simplify a result specialization.

There were many good comments and suggestions in this and the other thread, and I tried to incorporate them all. The new documentation is on trunk as of revision [80535].
