   8     <div style="margin-left: 0px;"> The <b>BOOST_PP_LIST_TO_SEQ</b> macro
   9       converts a <i>list</i> to a <i>seq</i>. </div>
  10     <h4> Usage </h4>
  11     <div class="code"> <b>BOOST_PP_LIST_TO_SEQ</b>(<i>list</i>) </div>
  12     <h4> Arguments </h4>
  13     <dl>
  14       <dt>list</dt>
  15       <dd> The <i>list</i> to be converted. </dd>
  16     </dl>
  17     <h4>Remarks</h4>
  18     <div> This macro uses <b>BOOST_PP_FOR</b>. Within <b>BOOST_PP_FOR</b>, it
  19       is more efficient to use <b>BOOST_PP_LIST_TO_SEQ_R</b>.<br>
  20       <br>
  21       If the <i>list</i> to be converted is empty, as represented by
  22       'BOOST_PP_NIL', the resulting <i>seq</i> is undefined since a <i>seq</i>
  23       cannot be empty.</div>
