Hi, I'm interesteed in a non preprocesor solution to the following transformation which bind N args in a mpl sequence (vector) to a boost:parameter:paramers signature. // bind to the signature the Args provided // template <typename Signature, typename... Args> // struct args; template <typename Signature, typename Args> struct args; template <typename Signature, typename Arg0> struct args<Signature, mpl::vector<Arg0> > { typedef typename Signature::template bind<Arg0>::type type; }; template <typename Signature, typename Arg0, typename Arg1> struct args<Signature, mpl::vector<Arg0, Arg1> > { typedef typename Signature::template bind<Arg0, Arg1>::type type; };* ... template <typename Signature, typename Arg0, typename Arg1, ..., typename ArgN> struct args<Signature, mpl::vector<Arg0, Arg1, ..., ArgN> > { typedef typename Signature::template bind<Arg0, Arg1, ..., ArgN>::type type; I supose that the C+0x variadic templates should allow a more compact definition. I would be interested in a non preprocesor solution to this transformation using boost. Is this possible? Can you help me? Thanks in advavance. _____________________ Vicente Juan Botet Escriba
