Inner function overload bug?

[Era Scarecrow]

 Hmmm...  Curious case, I think it's a bug; Depends on if inner 
functions qualify for overloading or not.

  //globally or in struct/class/union works fine
  int test() {return 0;}
  void test(int x) {}
  unittest {
    int test() {return 0;}
    void test(int x) {} //test already defined
  }

  void func() {
    int test() {return 0;}
    void test(int x) {} //test already defined

    static int test2() {return 0;}
    static void test2(int x) {}  //test2 already defined
  }
