- <h4>Lists</h4>
- <div> A <i>list</i> is a simple cons-style list with a head and a
- tail. The head of a <i>list</i> is an element, and the tail is
- either another <i>list</i> or <b>BOOST_PP_NIL</b>. For example, </div>
- <div class="code"> (<i>a</i>, (<i>b</i>, (<i>c</i>, <b>BOOST_PP_NIL</b>)))
- </div>
- <div> ...is a <i>list</i> of <i>3</i> elements--<i>a</i>, <i>b</i>, and <i>c</i>.
- </div>
- <div> This allows macro parameters to be variable in size and allows data
- states to change size without the user explicitly keeping track of the
- size independently.<br>
- <br>
- A list can be empty and therefore have a size of 0. An empty list is
- represented by the notation <b>BOOST_PP_NIL.<br>
- <br>
- </b></div>
- <div> Elements of a <i>list</i> can be extracted with <b>BOOST_PP_LIST_FIRST</b>
- and <b>BOOST_PP_LIST_REST</b>. </div>
