as for "why it's not working"... i honestly don't know. adding simple
`opAssign` overload to Tuple struct solves it:

  void opAssign(U, size_t n)(U[n] values)
  if (n == Types.length && allSatisfy!(isBuildableFrom!U, Types))
  {
      foreach (i, _; Types)
      {
          field[i] = values[i];
      }
  }

i guess that this was simply overlooked, so i think that you can create
ER for this.
