Another question might be: Is there any MACRO which gives me the ability to strip apart __VA_ARGS__? Such as giving me the count, or first argument? Cheers, Tim On Feb 4, 2008 1:36 PM, Ovanes Markarian wrote:

May be I misunderstand smth., but MACRO is pre-processor and takes place before compilation starts. mpl::size<...> is a template instantiation which takes place during compilation and after pre-processing.

Making pre-processor understand C++ templates is probably impossible (I think to write a compiler would be easier ;)

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);
