// A pointer to member can only be formed by `&T::m', however, other forms
// are ok for pointer to static member. Thus the error can only be determined
// after overload resolution. In template deduction, this can disambiguate
// otherwise ambiguous cases.

  static int f (int);
  int f (short);
  void baz ();
};

template <typename T> void foo (int (*)(T));      // ERROR - candidate
template <typename T> void foo (int (A::*)(T));   // ERROR - candidate

  foo (&A::f);  // ERROR - ambiguous
  foo (A::f);
  foo (&(A::f));
