In addition to these tests, I'd like to see a test for the following:
struct S {};
typedef S& SRef;

SRef operator++(SRef, int);

struct T {
  typedef T& TRef;
  TRef operator++(int);

struct U {
  typedef const U& ConstURef;
  ConstURef& operator++(int); // There's an extra ref shoved on here for fun.

struct V {
  V *operator++(int);
  V *const operator--(int);
