	<div style="margin-left:  0px;">
		The <b>BOOST_PP_LIST_TRANSFORM</b> macro transforms each element in a <i>list</i> according to a supplied transformation.
	</div>
	<h4>Usage</h4>
		<div class="code">
			<b>BOOST_PP_LIST_TRANSFORM</b>(<i>op</i>, <i>data</i>, <i>list</i>)
		</div>
	<h4>Arguments</h4>
		<dl>
			<dt>op</dt>
			<dd>
				A ternary predicate of the form <i>op</i>(<i>d</i>, <i>data</i>, <i>elem</i>).&nbsp;
				This transformation is expanded by <b>BOOST_PP_LIST_TRANSFORM</b> for each element in <i>list</i> with the next available <b>BOOST_PP_WHILE</b> iteration,
				the auxiliary <i>data</i>, and the current element in <i>list</i>.&nbsp;
			</dd>
			<dt>data</dt>
			<dd>
				Auxiliary data passed to <i>pred</i>.
			</dd>
			<dt>list</dt>
			<dd>
				The <i>list</i> to be transformed.
			</dd>
		</dl>
	<h4>Remarks</h4>
		<div>
			This macro expands <i>op</i> for each element in <i>list</i>.&nbsp;
			It builds a new <i>list</i> out of the results of each call.&nbsp;
			If, for example, <i>list</i> is (<i>a</i>, (<i>b</i>, (<i>c</i>, <b>BOOST_PP_NIL</b>))),
			this macro expands to...
			<div>
				(<i>op</i>(<i>d</i>, <i>data</i>, <i>a</i>), (<i>op</i>(<i>d</i>, <i>data</i>, <i>b</i>), (<i>op</i>(<i>d</i>, <i>data</i>, <i>c</i>), <b>BOOST_PP_NIL</b>)))
			</div>
		</div>
		<div>
			Previously, this macro could not be used inside <b>BOOST_PP_WHILE</b>.&nbsp;
			There is no longer any such restriction.&nbsp;
			It is more efficient, however, to use <b>BOOST_PP_LIST_TRANSFORM_D</b> in such a situation.
