I've implemented a LinkedList as a MutableSequence and __iadd__, which
is inherited from MutableSequence, does not perform as expected.
The _abcoll.py file contains this:
class MutableSequence(Sequence):
...
def __iadd__(self, values):
self.extend(values)
The method __iadd__ does not return anything, buy it should return
self. Right now, the sentence
aLinkedList += [1, 2]
sets the value of aLinkedList to None.
