/** <p>Repeats the macro <code>MACRO(INDEX,DATA)</code> for <code>INDEX = [FIRST,LAST)</code>.</p>

<p>In other words, expands to the sequence:</p>

<pre>
MACRO(FIRST,DATA) MACRO(BOOST_PP_INC(FIRST),DATA) ... MACRO(BOOST_PP_DEC(LAST),DATA)
</pre>

<p>For example,</p>

<pre>
#define TEST(INDEX,DATA) DATA(INDEX);
BOOST_PP_REPEAT_FROM_TO(4,7,TEST,X)
</pre>

<p>expands to:</p>

<pre>
X(4); X(5); X(6);
</pre>

<h3>2D and 3D repetition</h3>

<p>BOOST_PP_REPEAT_FROM_TO() implements automatic recursion. 2D and 3D repetition
are directly supported.</p>
