pylint #23986 False positive: E1101 [open]

This is pylint 1.9 on ubuntu lucid. I am inheriting from defaultdict, and in the implementation of my class I use defaultdict methods - they are all declared as non-existant. Example: from collections import defaultdict class IntDict(defaultdict): def __init__(self): defaultdict.__init__(self, int) def copy(self): result = IntDict() result.update(self) return result

Same kind of false positive here :
I'm using pyserial-2.5_rc2 with python 2.6.5 on Archlinux

import serial
a = serial.PARITY_NONE

E: 5: Module 'serial' has no 'PARITY_NONE' member

This is obviously false as I'm running this test successfully on my machine.

I get lots of these errors working with Google App Engine. It's pretty frustrating because they overwhelm warnings about real problems. When I do:
```
from google.appengine.ext import deferred
def f():
  pass
deferred.defer(f)
```
I get an error like:
```
[E1101, ...] Module 'google.appengine.ext.deferred' has no 'defer' member
```
But of course it does. This seems to happen in cases where the module has a __init__.py file with contents like:
```
from deferred import *
```
and also a deferred.py file:
```
def defer(callable, *args, **kwargs):
  ...
```

  hum pylint should be able to follow such things. May be the pb is related
  to relative import (eg 'from defererred import *' instead of
  'from google.appengine.ext.deferred import *').
  
  You can file a specific ticket for this pb.

I don't know if this is pertinent, but I get a E1101 false positive when using "self.__dict__['mykey'] = 'myvalue'" in place of self.mykey = 'myvalue'.

Hope it could help ...
