Odd indeed. My first reaction was: it is not needed because lists
support slicing, but when I tried to construct a list.get() using
slicing the best I could come up with was the following hack
>>> def lget(l, i, v): return (l[i:] or [v])
>>> lget(range(10), 20, 200)
>>> lget(range(10), 5, 50)
Yet for some reason I never missed this functionality ...
