Joel, I'm wondering what implications this would have for fusion containers. The variadic template tuple in: http://www.osl.iu.edu/~dgregor/cpp/variadic-templates.html is implemented roughly like fusion's cons; hence, I'm guessing it would be easy to use a slight modification of the that tuple to implement a variadic template fusion list. However, the fusion vector uses BOOST_PP_ENUM* to generate member names. To do that BOOST_PP_ENUM* requires the length of the variadic template typelist, information not available at preprocessing time. Hence, I'm wondering how a variadic template fusion vector would be implemented. Any ideas? TIA. -regards, Larry
