    //  Summary:

    //  A semantic action policy that insert data into an associative

    //  container using a const reference to data.

    //  (This doc uses convention available in actors.hpp)

    //

    //  Actions (what it does):

    //      ref.insert( T::value_type(value,value_ref) );

    //      ref.insert( T::value_type(T::key_type(first,last), value_ref));;

    //

    //  Policy name:

    //      insert_key_action

    //

    //  Policy holder, corresponding helper method:

    //      ref_const_ref_value_actor, insert_key_a( ref, value_ref );

    //

    //  () operators: both

    //

    //  See also ref_const_ref_value_actor for more details.
