It makes more sense to pass lists to frozensets since tuples need special syntax to be interpreted correctly in this context. For instance, the line "hr": frozenset(("noshade")) has a bug. It won't produce a frozenset with "noshade" but with ['a', 'e', 'd', 'h', 'o', 'n', 's'] because if you forget to add a comma at the end, the tuple won't be an iterable but the string is it interprets is.
