There is a Sequence ABC, but it does not define __add__.  It only defines
the following methods:
__contains__, __getitem__, __iter__, __len__, __reversed__, count, and index

tuple, range, and str types  all register as following the Sequence ABC.
list and bytearray types register as following the MutableSequence ABC,
which is a subclass of the Sequence ABC.
