Problem with testing `[]` is that if the checking logic has a bug, or a regression is introduced so that it only detects `]` instead of `[` the test would not detect that (but I guess that's a remote possibility).

Thanks for pointing it out, I'll add a valid array descriptor into the list of badInternalNames.
