   7 <div style="margin-left: 0px;"> The <b>BOOST_PP_TUPLE_TO_SEQ</b> macro
   8 converts a <i>tuple</i> to an <i>seq</i>. </div>
   9 <h4> Usage </h4>
  10 <div class="code"> <b>BOOST_PP_TUPLE_TO_SEQ</b>(<i>size</i>, <i>tuple</i>)<br>
  11 <br>
  12 or<br>
  13 <br>
  14 <b>BOOST_PP_TUPLE_TO_SEQ</b>(<i>...</i>) <a href="../topics/variadic_macros.html#VNotation" target="_self"><sup>(v)</sup></a><br>
  15 </div>
  16 <h4> Arguments </h4>
  17 <dl>
  18   <dt>size</dt>
  19   <dd>
  20                                 The size of the <i>tuple</i> to be converted.&nbsp;
  21                                 Valid <i>tuple</i> sizes range from <i>1</i> to <b>BOOST_PP_LIMIT_TUPLE</b>.&nbsp; </dd>
  22   <dt>tuple</dt>
  23   <dd> The <i>tuple</i> to be converted. </dd>
  24 </dl>
  25 <h4>Remarks</h4>
  26 <div> The <i>size</i> argument must be the actual size of the <i>tuple</i>.<br>
  27 <br>
  28 You can
  29 invoke the variadic version <a href="../topics/variadic_macros.html#VNotation" target="_self"><sup>(v)</sup></a> as BOOST_PP_TUPLE_TO_SEQ(<i>tuple</i>) or
