    <div style="margin-left:  0px;"> The <b>BOOST_PP_TUPLE_POP_FRONT</b> macro
      pops an element from the beginning of a <i>tuple</i>.</div>
    <h4>Usage</h4>
    <div class="code"> <b>BOOST_PP_TUPLE_POP_FRONT</b>(<i>tuple</i>) <a href="../topics/variadic_macros.html#VNotation"><sup>(v)</sup></a></div>
    <h4>Arguments</h4>
    <dl>
      <dt>tuple</dt>
      <dd> The <i>tuple</i> to pop an element from.</dd>
    </dl>
    <h4>Remarks</h4>
    <div> This macro returns <i>tuple</i> after removing the first
      element.&nbsp; If <i>tuple</i> has only a single element, it remains
      unchanged since a&nbsp;<i>tuple </i>must have at least one element.</div>
    <div> This macro uses <b>BOOST_PP_REPEAT</b> internally.&nbsp; Therefore,
      to use the <i>z</i> parameter passed from other macros that use <b>BOOST_PP_REPEAT</b>,
      see <b>BOOST_PP_TUPLE_POP_FRONT_Z</b> </div>
