 {{{
 struct F{
   template<typename Sig>
   struct result;
 };

 vector<int> const vec(5);
 invoke(F(),vec); // (1)

 int t(int i){ return i; }
 invoke(F(),transform(vec,&t)); // (2)

 }}}

 (1) uses F::result<F(int const &)>, while (2) uses F::result<F(int)>.
 I believe it should be (1) in both cases.

 attaching test case and patch, which converts each argument type using
 fusion::detail::call_param
