I think that's important. As OrderectDict has additional methods besides
the MutableMapping API, so TransformDict should provide useful

Ok, I have a better (IMO) proposal:
>>> d = TransformDict(str.casefold, {'Foo': 1})
>>> d.getitem('foo')
('Foo', 1)
>>> d.getitem('bar')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
KeyError: 'bar'
-1
When I want the canonical key, I'm not going to care about the value; and if I
do, it's easy enough to get.
