It's hard to write an autocompleter that does the right thing in all cases  

For a package, you have several sources for possibly valid attributes:

  - its dir() (that is, the package object's own attributes)
  - the __all__ attribute, when it exists
  - the list of modules inside the package directory or directories (given  
by its __path__ attribute)

Sometimes __init__.py is empty - and enumerating the modules inside the  
directory is the right thing to do. Sometimes the author explicitely  
imports things in __init__.py, things that comprise the public interfase  
to the package. In that case I'd not like to see "private" modules  
appearing in the list.
Combine with __all__, which might be defined or not. Mix all those, choose  
your own autocomplete algorithm, and see what happens...

__all__ isn't always defined. It's only used when you do "from xxx import
