   8                 The <b>BOOST_PP_LIST_REST_N_D</b> macro expands to a <i>list</i> of all but the first <i>count</i> elements of a <i>list</i>.&nbsp;
   9                 It reenters <b>BOOST_PP_WHILE</b> with maximum efficiency.

  23                                 The number of elements to remove from the beginning of <i>list</i>.
