[issue12606] Mutable Sequence Type works different for lists and bytearrays in slice[i:j:k]

del is not so flexible as assignement

>>> cmpr = [bytearray(i.encode('ascii')) for i in ('abcd', 'efgh', 'ijkl')]
>>> cmpr
[bytearray(b'abcd'), bytearray(b'efgh'), bytearray(b'ijkl')]
>>> cmpr[0][::-2] = cmpr[1][::2] = cmpr[2][1::2] = ()
>>> cmpr
[bytearray(b'ac'), bytearray(b'fh'), bytearray(b'ik')]
>>>
