Is there a MACRO which returns a constant when evaluating the size of an mpl sequence.

Here is what I'm trying to do:

#define MY_MACRO (N) CREATE_FOO_BAR_FN##N

#define SUPERFUNK (CLASSA, ...)\
     CLASSA { \
          typedef mpl::vector<__VA_ARGS__> v0; \
          MY_MACRO ( ??SOME_BOOST_MACRO??(mpl::size<v0>::value) ) \
    } \

If seems like this should be possible given that I can do the following:

BOOST_MPL_ASSERT_RELATION(mpl::size<v0>::value, ==, 0);
