#include <boost/preprocessor/list/transform.hpp>

#define BOOST_PP_LIST_TRANSFORM(F,P,L)

Applies the macro F(D,P,X) to each element X of the list producing a new list.

In other words, expands to:

  BOOST_PP_LIST_CONS(F(D,P,BOOST_PP_LIST_AT(L,0)),
  BOOST_PP_LIST_CONS(F(D,P,BOOST_PP_LIST_AT(L,1)),
  ...
  BOOST_PP_LIST_CONS(F(D,P,BOOST_PP_LIST_AT(L,BOOST_PP_DEC(BOOST_PP_LIST_SIZE(L)))),
  BOOST_PP_LIST_NIL) ... ))

For example,

  BOOST_PP_LIST_TRANSFORM(BOOST_PP_ADD_D,2,BOOST_PP_TUPLE_TO_LIST(2,(1,2)))

expands to the same as:

  BOOST_PP_TUPLE_TO_LIST(2,(3,4))
