In my development version, I now have this working! That is, you can do:

   std::cout << io::object
                (
                   std::make_pair( 'a', 5 ),
                   "{ " + fmt::pair()/" == " + " }"
                ) << '\n'; // output: { a == 5 }

and:

   std::cout << io::object
                (
                   std::make_pair( std::make_pair( 'a', 1 ), std::make_pair( 
'b', 2 )),
                   "{ " + fmt::pair
                   (
                      "< " + fmt::pair()/" + " + " >",
                      "( " + fmt::pair()/" | " + " )"
                   )/" = " + " }"
                ) << '\n'; // output: { < a + 1 > = ( b | 2 ) }

I have tested with VC 7.x and 8.0. VC7.0 has some problems, but the others 
build it fine.

Regards,
Reece
