NSDictionary won't work here (enums don't conform to NSCopying).
I could perhaps use a CFDictionaryRef here, but I'd like to know if is there any other way to achieve this.
NSMapTable using NSIntegerMapKeyCallBack. (The C API is recommanded when working with something else than object)

But CFDictionary is perfectly valid too.

You can also use NSDictionary with NSNumber keys. You'll just have to cast your enum values to one of the integer types.
