/** <p>Repeats the macro <code>M(I,P)</code> for <code>I = [S,E[</code>.</p>
|

|
|
|

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

|
<pre>
|

M(S,P) M(BOOST_PP_INC(S),P) ... M(BOOST_PP_DEC(E),P)

</pre>
|

<p>For example,</p>
|

|
|
|
||
|
|
<pre>
|

#define TEST(I,P) P(I);

</pre>
|

<p>expands to:</p>
