The <b>BOOST_PP_LIST_NIL</b> macro is a nil <i>list</i> constructor.
</div>
<h4>Usage</h4>
<div class="code">
<b>BOOST_PP_LIST_NIL</b>
</div>
<h4>Remarks</h4>
<div>
This macro represents the end of a <i>list</i>.
</div>
<div>
This macro is no longer necessary.&nbsp;
It simply expands to <b>BOOST_PP_NIL</b>.&nbsp;
Because of this, this macro is deprecated.
