Message1023

A class created with multiple inheritance from a built-in type and a 
non built-in type has faulty method look-up. 

For example:

>>>  class myClass:
...    def foo(self):
...      print "myClass foo called."

>>> class myMulti(dict, myClass):
...    pass
...

>>> t = myMulti()
>>> type(t)
<class '__main__.myMulti'>

>>> t.foo()
Traceback (innermost last):
  File "<console>", line 1, in ?
AttributeError: 'dict' object has no attribute 'foo'


If the order or the inheritance is changed a java ClassCastException 
is thrown at class creation.

>>> class myMulti2(myClass, dict):
...    pass
... 
Traceback (innermost last):
  File "<console>", line 1, in ?
java.lang.ClassCastException
