First of all you shouldn't type check. Second, if you really need to its not that difficult to figure out the return type of the factory function. Its certainly much easier to understand than instantiating a class and then magically not getting an instance of that class. -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
