### #define BOOST_PP_ENUM(COUNT,MACRO,DATA)

Generates a comma separated list.

In other words, expands to the sequence:

    MACRO(0,DATA), MACRO(1,DATA), ..., MACRO(BOOST_PP_DEC(COUNT),DATA)

For example,

    #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(3,TYPED_PARAM,(X,x))

expands to:

    X0 x0, X1 x1, X2 x2

### 2D and 3D repetition

BOOST_PP_ENUM() implements automatic recursion. 2D and 3D repetition are directly supported.
