not

  static
  int
  method ()
  {
    return 42;
  }

rather

  static
  int
  method ()
  {
      static int count = 0;				      // <-- THIS STATIC
      printf ("method() has been called %d times\n", count++);
      return 42;
  }

ruby static -> evaluated once, and once only, in the enclosing scope where
'enclosing scope' is subject to modification as per your 'block local' rules
and where they are headed.
