void append(T, Args...)(ref T[] arr, auto ref Args args){
{
   static if (args.length == 1)
      arr ~= args[0];     // inlined
   else{
      arr.length += args.length;
      foreach(i, e; args)
         arr[$ - args.length + i] = e;
   }
}

I've just tested, this looks usable.
Equal for 1 item, considerably (~40%) faster for 2, and much (100+%) faster for more.
Also more convenient.

Maybe samthing like that should go to Fobos.
