One good thing for safety and CTFE is allow multiple return value. In
combination with `auto ref` it is _very_ powerful:

----
auto ref front()
{
  // Returns 2 values, each value is returned by reference if possible
  return (a.front, b.front);
}

auto ref front() {
    return tuple(a.front, b.front);
