0019     //  Summary:
0020     //  A semantic action policy that insert data into an associative
0021     //  container using a const reference to data.
0022     //  (This doc uses convention available in actors.hpp)
0023     //
0024     //  Actions (what it does):
0025     //      ref.insert( T::value_type(value,value_ref) );
0026     //      ref.insert( T::value_type(T::key_type(first,last), value_ref));;
0027     //
0028     //  Policy name:
0029     //      insert_key_action
0030     //
0031     //  Policy holder, corresponding helper method:
0032     //      ref_const_ref_value_actor, insert_key_a( ref, value_ref );
0033     //
0034     //  () operators: both
0035     //
0036     //  See also ref_const_ref_value_actor for more details.
