``MutableSequence``
A subclass of ``Sequence`` adding some standard mutating methods.
Abstract mutating methods: ``__setitem__`` (for integer indices as
well as slices), ``__delitem__`` (ditto), ``insert``, ``append``,
``reverse``. Concrete mutating methods: ``extend``, ``pop``,
well as slices), ``__delitem__`` (ditto), ``insert``. Concrete
mutating methods: ``append``, ``reverse``, ``extend``, ``pop``,
``remove``. Concrete mutating operators: ``+=``, ``*=`` (these
mutate the object in place). **Note:** this does not define
``sort()`` -- that is only required to exist on genuine ``list``
