Hey I'm trying to create a macro using Boost's preprocessor library that has nested BOOST_PP_LIST_FOR_EACH's. Something akin to this:
#define MACRO2(r,data,elem) elem
#define MACRO1(r,data,elem) BOOST_PP_LIST_FOR_EACH(MACRO2,NULL,elem)

#define LIST ( (1,(2,(3,BOOST_PP_NIL))), ( (4,(5,(6,BOOST_PP_NIL))), BOOST_PP_NIL ) )


But it doesn't work - the first FOR_EACH works fine but the nested one isn't expanded. Any ideas? [UPDATE] I managed to find a solution for the problem by rearranging the order things are done in - basically placing the FOR_EACH directly inside MACRO in place of LIST.
