Decode fd_set into array of file descriptors

Yes that would be my suggestion. [a, b, c] could just mean a
collection that consists of a, b, c. So an fd_set or signal mask
represented as [a, b, c] seems just as interpretable to me as [a b c]
even under bitwise operations like ~. For example, with the fd_set
bitset I only want to see a list of file descriptors.
