<div style="margin-left: 0px;">
The <b>BOOST_PP_LIST_TO_TUPLE_R</b> macro converts a <i>list</i> to a <i>tuple</i>.
It reenters <b>BOOST_PP_FOR</b> with maximum efficiency.
</div>
<h4>Usage</h4>
<div class="code">
<b>BOOST_PP_LIST_TO_TUPLE_R</b>(<i>r</i>, <i>list</i>)
</div>
<h4>Arguments</h4>
<dl>
<dt>r</dt>
<dd>
The next available <b>BOOST_PP_FOR</b> repetition.
</dd>
<dt>list</dt>
<dd>
The <i>list</i> to be converted.
</dd>
</dl>
<h4>Remarks</h4>
<div>
If <i>list</i> is, for example, (<i>a</i>, (<i>b</i>, (<i>c</i>, <b>BOOST_PP_NIL</b>))),
this macro will produce:
<div>
(<i>a</i>, <i>b</i>, <i>c</i>)
</div>
