    I'd say 2)
    Underscore is legal and I think period is not. And the $ character is used internally for anonymous classes and the like so I'd bet that is legal too.

    @cafecortado Well done, well done... Yes, 2) is correct. And indeed, period is not legal, while underscore and $ are.

    Came here to make the same guess as @cafecortado

    It makes sense that . is not legal, otherwise it would conflict with the member access syntax.
