Hi,

It is there. See my example above.

While io.hpp includes the appropriate operator<<, it defines it in namespace fusion and fusion::operators. Since the code generated from struct adaptation appears to reside in fusion::traits and fusion::extension, I'm guessing that adapted structs don't have ADL kicking in. Placing a 'using boost::fusion::operators::operator<<;' declaration in namespace demo is one way to fix the problem. HTH, Nate
