You need to use a real parser as Ronald indicated:

    [ #test
    1   ,
    ]

Also, I agree with Ronald that "$[foo bar]" overall makes more sense with
Python.  (This is my opinion as someone who has done functionally zero
ObjC programming but with more than ten years of Python.)  However,
because there's essentially zero chance of getting this integrated into
Python it doesn't much matter.
