Wow, thanks Steven. This is exactly what I'm looking for. Although, I
find the name BOOST_PP_SEQ_ENUM a bit odd.
Everything works now. And yes, there are way too many template
instantiations. ;-)

Hi there, thanks Steven for your good advise. I have been making some progress but I'm stuck on one part. Here is some code that exhibits my problem.
#include
template< int i, int j > void test() {}
int main() { #define S1 (1)(2)(3) #define S2 (1)(2)(3) #define FOR_EACH( r, data, elem ) BOOST_PP_CAT( elem \ , BOOST_PP_COMMA() )
#define FOR_EACH_PRODUCT(r, product) test< BOOST_PP_SEQ_FOR_EACH( FOR_EACH \ , BOOST_PP_EMPTY() \ , product \ ) >();
BOOST_PP_SEQ_FOR_EACH_PRODUCT( FOR_EACH_PRODUCT \ , (S1)(S2) \ )
return 0; }
Here is what the preprocessor produces:
test< 1, 1, >(); test< 1, 2, >(); test< 1, 3, >(); test< 2, 1, >(); [snip]
My problem is that I cannot figure out how to get rid of the last comma? Any ideas?
BOOST_PP_SEQ_ENUM?
In Christ, Steven Watanabe
