Boost.Optional has some interaction with (including initialization from) boost::none, which seems to correspond to your "undef".
Good point, but I would also like to see overloaded == and != operators using boost::none.
That is already supported.
I think this is another documentation problem. http://www.boost.org/libs/optional/doc/optional.html shows a constructor and operator= using boost::none, but no operators == or !=. But you are right that the functionality is supported in the library.
