[Python-Dev] Uninformative error message about subclassing

[Edward C. Jones]

Here are two small python files:

----
a.py:

class A(object):
    pass

----
b.py:

import a

class B(a):
    pass
----
If I run "python b.py" I get the uninformative error message:

Traceback (most recent call last):
  File "./b.py", line 5, in ?
    class B(a):
TypeError: function takes at most 2 arguments (3 given)

I think the message should say that "a" is not a class.
