| <h4>Tuples</h4> |
| <div> A <i>tuple</i> is a simple comma-separated list of elements inside |
| parenthesis. For example, </div> |
| <div class="code"> (<i>a</i>, <i>b</i>, <i>c</i>) </div> |
| <div> ...is a <i>tuple</i> of <i>3</i> elements--<i>a</i>, <i>b</i>, and |
| <i>c</i>. </div> |
| <div> <i>Tuples</i> are fast and easy to use. With variadic macro |
| support it is not necessary to know the size of a <i>tuple; </i>without |
| variadic macro support all access to <i>tuples</i> requires |
| knowledge of its size. Use a <i>tuple </i>instead of an <i>array</i> if |
| your compiler supports variadic macros, since a <i>tuple </i>has all of |
| the functionality as an <i>array </i>and is easier syntactically to use.</div> |
| <div> Elements of a <i>tuple</i> can be extracted with <b>BOOST_PP_TUPLE_ELEM</b>. |
| </div> |
