(The "get attribute" and "set attribute" methods are still called __get__ and __set__, respectively.) +- Some subtle issues with the super built-in were fixed: + + (a) When super itself is subclassed, its __get__ method would still + return an instance of the base class (i.e., of super). + + (b) super(C, C()).__class__ would return C rather than super. This + is confusing. To fix this, I decided to change the semantics of + super so that it only applies to code attributes, not to data + attributes. After all, overriding data attributes is not + supported anyway. + + (c) The __get__ method didn't check whether the argument was an + instance of the type used in creation of the super instance. + + Core and builtins Extension modules |
