Re: [Boost-users] [type_traits] will the future has_operator_left_shift be able to test if a type is serializable to a stream ?

...

BOOST_STATIC_ASSERT(( boost::has_operator_left_shift<  std::ostream, int>::value ));

This one still produces the following warning (with both vc80 and vc100) :

boost/type_traits/detail/has_binary_operator.hpp(102): warning C4913: user defined binary operator ',' exists but no overload could convert all operands, default built-in binary operator ',' used          boost/type_traits/detail/has_binary_operator.hpp(136)

What says this warning is fine (by the way I have been able to reproduce it with VC++ 2010). It describes well what happen. I do not know if it is possbile to remove the warning. Nevertheless, what is important is that the result is now 'true'. I am getting closer to the review. Frédéric
