   8                 The <b>BOOST_PP_LIST_CAT</b> macro concatenates all elements in a <i>list</i>.
   9         </div>
  10         <h4>Usage</h4>
  11                 <div class="code">
  12                         <b>BOOST_PP_LIST_CAT</b>(<i>list</i>)
  13                 </div>
  14         <h4>Arguments</h4>
  15                 <dl>
  16                         <dt>list</dt>
  17                         <dd>
  18                                 The <i>list</i> whose elements are to be concatenated.
  19                         </dd>
  20                 </dl>
  21         <h4>Remarks</h4>
  22                 <div>
  23                         Elements are concatenated left-to-right starting with index <i>0</i>.
  24                 </div>
  25                 <div>
  26                         Previously, this macro could not be used inside <b>BOOST_PP_WHILE</b>.&nbsp;
  27                         There is no longer any such restriction.&nbsp;
  28                         It is more efficient, however, to use <b>BOOST_PP_LIST_CAT_D</b> in such a situation.
  29                 </div>
