Thanks for the tips.

It can not exclude static function, so I replace it with 
typeof(&__traits(getMember, S.init, "kill"));

Still, if there is multi kill methods,  then I need a array to 
handle them.

  struct S {
      bool kill() {
       return true;
     }
      bool kill(int id) {
       return true;
     }
  }
