The <b>BOOST_PP_LIST_CAT</b> macro concatenates all elements in a <i>list</i>.
</div>
<h4>Usage</h4>
<div class="code">
<b>BOOST_PP_LIST_CAT</b>(<i>list</i>)
</div>
<h4>Arguments</h4>
<dl>
<dt>list</dt>
<dd>
The <i>list</i> whose elements are to be concatenated.
</dd>
</dl>
<h4>Remarks</h4>
<div>
Elements are concatenated left-to-right starting with index <i>0</i>.
</div>
<div>
Previously, this macro could not be used inside <b>BOOST_PP_WHILE</b>.
There is no longer any such restriction.
It is more efficient, however, to use <b>BOOST_PP_LIST_CAT_D</b> in such a situation.
