I will look at this but please look at my variadic macro data library in the sandbox which attempts to solve this same problem.
I do not see vmd_size.hpp. Where should I look?
Look at BOOST_VMD_IS_EMPTY(...). I did not attempt to use BOOST_VMD_IS_EMPTY(...) on BOOST_VMD_DATA_SIZE(...) to return 0 for empty variadic data because of the innate flaw in BOOST_VMD_IS_EMPTY, for which there is no workaround. You can obviously use it as you wish, for your own macro testing the size of variadic data. Also, for VC8, I could not implement a BOOST_VMD_IS_EMPTY(...) taking variadic data and had to settle for a BOOST_VMD_IS_EMPTY(param) instead. I did use BOOST_VMD_IS_EMPTY on my new BOOST_VMD_ASSERT macros while documenting the flaw in BOOST_VMD_IS_EMPTY.
When I announced the latest update to my library, nobody paid any attention to it.
Everything comes when time is right ;).
