2D and 3D repetition

2D and 3D repetition are supported with the BOOST_PP_REPEAT_2ND() and BOOST_PP_REPEAT_3RD() macros. For example, 
\verbatim
  // A generalized macro for generating 2D arrays
  #define ARRAY_2D(W,H,M,P)\
    BOOST_PP_REPEAT_2ND\
    ( H\
    , ARRAY_2D_ROW\
    , (W,H,M,P)\
    )
  #define ARRAY_2D_ROW(Y,WHMP)\
    BOOST_PP_EXPAND\
    ( BOOST_PP_REPEAT\
      ( BOOST_PP_TUPLE_ELEM(4,0,WHMP)\
      , ARRAY_2D_ELEM\
      , (Y,BOOST_PP_TUPLE4_ENUM WHMP)\
      )\
    )
  #define BOOST_PP_TUPLE4_ENUM(A,B,C,D) A,B,C,D
  #define ARRAY_2D_ELEM(X,YWHMP)\
    BOOST_PP_TUPLE_ELEM(5,3,YWHMP)\
    BOOST_PP_EXPAND\
    ( ( X\
      , BOOST_PP_TUPLE_ELEM(5,0,YWHMP)\
      , BOOST_PP_TUPLE_ELEM(5,1,YWHMP)\
      , BOOST_PP_TUPLE_ELEM(5,2,YWHMP)\
      , BOOST_PP_TUPLE_ELEM(5,4,YWHMP)\
      )\
    )

  // Here we use the above macro to generate something
  #define ELEM(X,Y,W,H,E) BOOST_PP_COMMA_IF(BOOST_PP_OR(X,Y)) E##_##X##_##Y

  ARRAY_2D(3,4,ELEM,elem)
\endverbatim
expands to: 
\verbatim
  elem_0_0, elem_1_0, elem_2_0,
  elem_0_1, elem_1_1, elem_2_1,
  elem_0_2, elem_1_2, elem_2_2,
  elem_0_3, elem_1_3, elem_2_3
\endverbatim
Since recursive expansion of macros is not allowed by the C++ preprocessor, replacing the BOOST_PP_REPEAT_2ND above with BOOST_PP_REPEAT, would not produce the above expansion.
