Title:
  Problem with Pylint's handling on __all__

Status in pylint package in Ubuntu:
  Invalid

Bug description:
  Binary package hint: pylint

  The following example code illustrates two surprises with Pylint's handling of __all__.
  1. Including an nonexistant member should raise an error.
  2. republishing an imported member in __all__ should not raise a warning that the import was unused.

  
  """Test Pylint's use of __all__.

  * NonExistant is not defined in this module, and it is listed in
    __all__. An error is expected.

  * This module imports path and republished it in __all__. No errors
    are expected.
  """
  from os import path

  __all__ = [
    'Dummy',
    'NonExistant',
    'path',]

  
  class Dummy:
    """A class defined in this module."""
