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 <boost/tr1/tuple.hpp> or <tuple>. Is this another VC9 bug? I could not find the compiler flag which hinders M$'s implementation of TR1 ...

Any pointer appreciated.

Unfortunately there are no << and >> operators for tuple types in the TR1 spec (although it may have been in the original proposal paper). John.
