The built-in isinstance function is still broken when used on extension classes. For example: >>> from ExtensionClass import Base >>> class Super: ... pass ... >>> isinstance(Super(), Base) Traceback (most recent call last): File "<stdin>", line 1, in ? TypeError: isinstance() arg 2 must be a class or type isinstance() should allow any object as the first argument and a class, a type, or something with a __bases__ tuple attribute for the second argument.
