[Boost-users] [serialization|TR1] serialization impementation for std::tr1::tuple?

Hi! Sorry, if this has been discussed before. I am too stupid (and tired) to find the equivalent for tuple_io.hpp for the boost tr1::tuple implementation. So is there already some serialization and/or I/O implementation for a tr1::tuple available somewhere? The proposal at http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2002/n1403.pdf mentions operator<<, but VC9 SP1 refuses to find one if I #include or <tuple>. Is this another VC9 bug? I could not find the compiler flag which hinders M$'s implementation of TR1 ... Any pointer appreciated. best regards, Markus
