      6    Mapped arguments object mutation via alias during traversal using for..of
      7 info: |
      8    "Mapped" arguments objects should be able to be traversed using a `for..of`
      9    loop, and dynamic changes to the formal parameters should be reflected in
     10    the iterated values.
