The Python developers seem to agree with you and have made the compiler 
smart enough to accomodate your expectations in Python 3.3:

$ cat tmp.py
class Outer:
    class Inner:
        pass

print(Outer.Inner)
$ python3.2 tmp.py
<class '__main__.Inner'>
$ python3.3 tmp.py
<class '__main__.Outer.Inner'>
