The new (in 3.0 and maybe 2.6, but undocumented) special methods instancecheck and subclasscheck let one overload the default behavior of isinstance and issubclass.

That's fine for 3.0, but I don't think the current behaviour should be removed from any 2.x version, as it would make writing code that works over multiple 2.x versions difficult.
