Fusion provides supprot for thing like boost::tuple or boost::array to be treated as fusion sequence in runtime algorithm. Is there any meta-function that gives me the compile-time conversion or should I build them myself ? eg as_vector< array >::type == vector Thanks in advance -- ___________________________________________ Joel Falcou - Assistant Professor PARALL Team - LRI - Universite Paris Sud XI Tel : (+33)1 69 15 66 35
