Summary: no __methods__ for lists, strings etc.

Initial Comment:
With Python 2.2a2+ from cvs, [].__methods__ fails with

AttributeError: 'list' object has no attribute
'__methods__'

Same for a string or a dictionary.

The Library Reference section on "Special Attributes"
(2.1.9 here) still recommends [].__methods__ for
finding out about an object's methods.

dir([]) returns [] and doesn't list the attributes
either.

OK, I can use [].__class__.__dict__.keys() -- but it's
not very intuitive ...

Reassigned to me.  __members__ and __methods__ were always 
ugly hacks, and we'd like to get rid of them.  I'm making 
dir() "smarter" again, so that dir([]) will be more 
informative (see bug 449989).

Until then, try using dir(type([])) (more generally, dir
(type(object)) instead of the atrocious 
[].__class__.__dict__.keys().
