/** <p>Generates a comma separated shifted list.</p>

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

<pre>
  MACRO(1,DATA), MACRO(2,DATA), ..., MACRO(BOOST_PP_DEC(COUNT),DATA)
</pre>

<p>For example,</p>

<pre>
  #define TYPED_PARAM(INDEX,DATA)\
    BOOST_PP_CAT(BOOST_PP_TUPLE_ELEM(2,0,DATA),INDEX) BOOST_PP_CAT(BOOST_PP_TUPLE_ELEM(2,1,DATA),INDEX)
  BOOST_PP_ENUM_SHIFTED(3,TYPED_PARAM,(X,x))
</pre>

<p>expands to:</p>

<pre>
  X1 x1, X2 x2
</pre>

<h3>Uses</h3>
<ul>
  <li>BOOST_PP_REPEAT()</li>
