For certain applications, you want to unpack repeatedly the same pattern. This came in issue17618 (base85 decoding), where you want to unpack a stream of bytes as 32-bit big-endian unsigned ints. The solution adopted in issue17618 patch (struct.Struct("!{}I")) is clearly suboptimal. I would suggest something like a iter_unpack() function which would repeatedly yield tuples until the bytes object is over.
