function x() {
  arguments("a", "b", "c");
  
  function arguments(x, y, z) {
      print(arguments)
  }
}
x()

This is expected to print "[object Arguments]" - a function doesn't define its own name as a symbol in its own environment record (ES 5.1, section 10.5), therefore "arguments" in function "arguments" has to refer to the "arguments" object.
