> I like it! But "decorator" isn't a good name - it describes how it's
> being done, rather than what is being done. How about "key"? After
> all, "key=str.lower" reads more or less as "the key is the lowercase
> equivalent of the value", and "key=ages.__getitem__" reads "get the
> key by getting the appropriate item from the ages dictionary".

Agreed, that was my first thought too.
