The only thing I could imagine as possibly useful would be std::vector v = { 1, 2, 3 }; but I think the benefit of that is quite low as well since it is syntactic sugar for template inline std::vector make_vector(std::initializer_list il) { return std::vector(il); } auto v = make_vector({ 1, 2, 3 }); /MF -- --- You received this message because you are subscribed to the Google Groups "ISO C++ Standard - Future Proposals" group.
