If I wanted to implement a list-like class that doesn't show it's elements at

For example:
hl = HiddenList(1,2,3)
hl
<HiddenList object: length=3>
hl[1]
2
(Implementation of HiddenList left as an exercise for the reader.)
And just so some of you who wonder how hard this implementation is:
(2.4.X, 2.5.X, 2.6.X):
class HiddenList(list):
def __repr__(self):
return '<%s object: length=%s>' % (
type(self).__name__, len(self))
(3.0):
class HiddenList(list):
def __repr__(self):
return '<{0} object: length={1}>'.format(
type(self).__name__, len(self))
