For a start the potentially infinite list of attributes handled by
__getattr__ or __getattribute__:
>>> class C(object):
def __getattribute__(self, name):
if name.startswith('weird'):
return 42
>>> c = C()
>>> c.weirdattribute
42
>>> dir(c)
[]
Any objects which are actually implemented as C extensions are quite likely
to have attributes that dir() cannot see.
