Is there a way to return an lvalue and also an rvalue from the same member function?

Hi,

struct S{
  int[2] array;
  ref  x()       { return array[0]; }
  auto x() const { return array[0]; }
}

If there a way to write the function 'x' into one function, not 2 
overloads.

I tried auto/const/ref mindlessly :D, also remembered 'inout', 
but obviously those weren't solve the problem.

(This is going to be a swizzling 'system' that mimics GLSL, later 
I will make a template that takes 'x'as a template parameter, 
just wondering that the support for const and non-cons can be 
done easier.)
