Because a two-line wrapper goes a long way?

Python 2.2 (#28, Dec 21 2001, 12:21:22) [MSC 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> class myList(list):
...     len = list.__len__
...
>>> l = myList([1,2,3,4])
>>> l
[1, 2, 3, 4]
>>> l.len()
4
>>> l.extend([5,6,7])
>>> l.len()
7
