o is a repetition construct.&nbsp; If <i>seq</i> is (<i>a</i>)(<i>b</i>)(<i>c</i>), 
			it expands to the sequence:
			<div>
				<i>macro</i>(<i>r</i>, <i>data</i>, <i>a</i>) <i>macro</i>(<i>r</i>, <i>data</i>,
				<i>b</i>) <i>macro</i>(<i>r</i>, <i>data</i>, <i>c</i>)
			</div>
		</div>
		<div>
			For maximum efficiency, use <b>BOOST_PP_SEQ_FOR_EACH_R</b>.
		</div>
