New submission from poelzi: The Decimal class doesn't use lookups through self to construct results in functions like __add__ to generate the resulting object. This makes subclassing Decimal more or less senseless since all methods have to be wrapped instead of overriding the __new__ and __init__ methods, which could be enough for immutable type. Currently I'm implementing a Money class which is more or less a Decimal with addition currency information. Because resulting Types generated with something like return Decimal(something) instead of self.__new__(...)
