Ah, yeah, no worries! I was not :)

It's actually an interesting thread. My take would have been to use comma when it's something we intend to modify, no comma when it's not. So intent is explicit.

Like:

    STATES = [
      :success,
      :error
    ]

    SUPPORTED_LANGUAGES = [
      "en",
      "es",
      "fr",
    ]
