Anyone has a nice "view_var" procedure ?

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.
