| <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. |
| </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> |
