All types in 2.2 inherit from object, including int. >>> class IntWithA(int): ... def seta(self, value): ... self._a = value ... def geta(self): ... return self._a * 2 ... a = property(geta, seta) ... >>> i = IntWithA(42) >>> i 42 >>> i.a = 333 >>> i.a 666 >>> range(50)[i] 42 >>> So, e.g., adding arbitrary properties should be a crawl in the park. > I'm also wondering how to make a rank-0 Float array fail as an index. Quit while you're ahead <wink>. The obvious idea is to make a Rank0FloatArray type which is not a subclass of int.
