  19     //  Summary:
  20     //  A semantic action policy that insert data into an associative
  21     //  container using a const reference to data.
  22     //  (This doc uses convention available in actors.hpp)
  23     //
  24     //  Actions (what it does):
  25     //      ref.insert( T::value_type(value,value_ref) );
  26     //      ref.insert( T::value_type(T::key_type(first,last), value_ref));;
  27     //
  28     //  Policy name:
  29     //      insert_key_action
  30     //
  31     //  Policy holder, corresponding helper method:
  32     //      ref_const_ref_value_actor, insert_key_a( ref, value_ref );
  33     //
  34     //  () operators: both
  35     //
  36     //  See also ref_const_ref_value_actor for more details.
