Hi I want to write a function like that template<class A, class T0, class T1, ..., class Tn> execute(const A& a, T0& arg0, T1& arg&, .. , Tn& argn) {     boost::fusion::vector<T0,...,Tn> vec(arg0, arg1, .., argn);     /* rest of the code */ } Can anybody guide me how can I write this function without overloading it with different number of args? Thanks in anticipation Noman Javed
