This is not the same as list.extend because it makes a separate
intermediate list instead of doing the extension completely in place.
However, the following does mimic .extend.
>>> s=range(5)
>>> s[len(s):] = list('abc')
>>> s
[0, 1, 2, 3, 4, 'a', 'b', 'c']
So. at the cost of writing and calling len(s), you are correct that .extend
is not necessary.
