	<div style="margin-left:  0px;">
		The <b>BOOST_PP_LIST_FOR_EACH_I</b> macro repeats a macro for each element in a <i>list</i>.
	</div>
	<h4>Usage</h4>
		<div class="code">
			<b>BOOST_PP_LIST_FOR_EACH_I</b>(<i>macro</i>, <i>data</i>, <i>list</i>)
		</div>
	<h4>Arguments</h4>
		<dl>
			<dt>macro</dt>
			<dd>
				A macro of the form <i>macro</i>(<i>r</i>, <i>data</i>, <i>i</i>, <i>elem</i>).&nbsp;
				This macro is expanded by <b>BOOST_PP_LIST_FOR_EACH_I</b> with each element in <i>list</i>.&nbsp;
				It is expanded with the next available <b>BOOST_PP_FOR</b> repetition, the auxiliary <i>data</i>, the index of the current element, and the current element.
			</dd>
			<dt>data</dt>
			<dd>
				Auxiliary data passed to <i>macro</i>.
			</dd>
			<dt>list</dt>
			<dd>
				The <i>list</i> for which <i>macro</i> will be invoked on each element.
			</dd>
		</dl>
	<h4>Remarks</h4>
		<div>
			This macro is a repetition construct.&nbsp;
			If <i>list</i> is (<i>a</i>, (<i>b</i>, (<i>c</i>, <b>BOOST_PP_NIL</b>))), it expands to the sequence:
			<div>
				<i>macro</i>(<i>r</i>, <i>data</i>, <i>0</i>, <i>a</i>) <i>macro</i>(<i>r</i>, <i>data</i>, <i>1</i>, <i>b</i>) <i>macro</i>(<i>r</i>, <i>data</i>, <i>2</i>, <i>c</i>)
			</div>
		</div>
		<div>
			Previously, this macro could not be used inside <b>BOOST_PP_FOR</b>.&nbsp;
			There is no longer any such restriction.&nbsp;
			It is more efficient, however, to use <b>BOOST_PP_LIST_FOR_EACH_I_R</b> in such a situation.
