Hi:

When I am reading mpl source code. I notice that push_bck algorithm, Look as following:
template<>
struct push_back_traits< aux::vector_tag >
{
    template< typename Vector, typename T > struct algorithm
    {
        typedef vector_node<T,Vector> type;
    };
};

My question is: when generate new sequence, vactor_node<T, vector>, why skip "size" argument ?
How does it increase sequence size in push_back? 

About push_front, It increase sequence size when generating new sequence.

Regard

Karl
