hi,
in an ealier post, i was helped to write explicit template instantiations as:

#define FINH1 (EC)(EP)(AC)(AP)
#define FINH2 (C)(D)(E)(F)(G)
#define FINH3 (2)(3)
#define M(r, product) template class Tree<BOOST_PP_SEQ_ENUM(product)>;
BOOST_PP_SEQ_FOR_EACH_PRODUCT(M, (FINH1)(FINH2)(FINH3))

That nicely generated:
template class Tree<EC,C,2>;
template class Tree<EC,C,3>;
template class Tree<EC,D,2>;
template class Tree<EC,D,3>;
...

what i need now is coupling FINH2 and FINH3  (i don't want their crossproduct) as in:
#define FINH1 (EC)(EP)(AC)(AP)
#define FINH2 (C,2)(D,2)(E,3)(F,3)(G,3)

#define M(r, product) template class Tree<BOOST_PP_SEQ_ENUM(product)>;
BOOST_PP_SEQ_FOR_EACH_PRODUCT(M, (FINH1)(FINH2))

But that does't work because the commas in FINH2 are taken as macro arguments which fails...

ideas are appreciated...

regards,
