[Python-Dev] Should issubclass() be more like isinstance()?

While nocking together a framework today, I ran into the amazing
limitations of issubclass().

A) issubclass() throws a TypeError if the object being checked is not
a class, which seems very strange. It is a predicate, and lacking a
isclass() method, it should just return False.
B) issubclass() won't work on a list of classs, the way isinstance() does.

Is there any support for patches which fix A and/or B?
