New submission from Ram Rachum:
Implement `__getitem__` on `OrdredDict.keys`, `OrdredDict.values` and
`OrdredDict.items`, so the following code snippet wouldn't error:
>>> from collections import OrderedDict
>>> o = OrderedDict(((1, 2), (3, 4), (5, 6)))
>>> o
OrderedDict([(1, 2), (3, 4), (5, 6)])
>>> o.keys()
KeysView(OrderedDict([(1, 2), (3, 4), (5, 6)]))
>>> o.keys()[0]
Traceback (most recent call last):
File "<string>", line 1, in <fragment>
builtins.TypeError: 'KeysView' object does not support indexing
>>> o.values()[0]
Traceback (most recent call last):
File "<string>", line 1, in <fragment>
builtins.TypeError: 'ValuesView' object does not support indexing
>>> o.items()[0]
Traceback (most recent call last):
File "<string>", line 1, in <fragment>
builtins.TypeError: 'ItemsView' object does not support indexing
