[Boost-users] adding elements to a std::container in a single expression

until now I've usually written my own template to do this: template<typename T> struct push_back_container:T { push_back_container &_push_back(const typename T::value_type &_r) { push_back(_r); return *this; } }; one can use this like this: push_back_container

()._push_back(something1)._push_back(_something2)

Is there some more elegant way to do this? Peter
