 mapping rather than a sequence because the lookups use arbitrary
 :term:`immutable` keys rather than integers.
 
+ The :class:`collections.abc.Sequence` abstract base class
+ defines a much richer interface that goes beyond just
+ :meth:`__getitem__` and :meth:`__len__`, adding :meth:`count`,
+ :meth:`index`, :meth:`__contains__`, and
+ :meth:`__reversed__`. Types that implement this expanded
+ interface can be registered explicitly using
+ :func:`~abc.register`.

 slice
 An object usually containing a portion of a :term:`sequence`. A slice is
 created using the subscript notation, ``[]`` with colons between numbers
