Actually, lists are OK too, it is just new tables that can't be introduced
on the right hand side of an access(5) lookup.

You just can't start a list with one of the built-in access(5) keywords
that is also a restriction list building block:

        reject
        defer
        defer_if_reject
        defer_if_permit

since these will be treated as an "ACTION <optional text>" form rather
than a "restriction, restriction, ..." list.
