list.clear() missing?!?

It's not even clear that extend needs two lines:

 >>> s = range(5)
 >>> more = list('abc')
 >>> s[:] = s + more
 >>> s
[0, 1, 2, 3, 4, 'a', 'b', 'c']

Okay, it's not obvious, but I don't think s[:]=[] is really any more 
obvious as a way to clear the list.

Clearly .extend() needs to be removed from the language as it is an 
unnecessary extension to the API using slicing, which everyone should 
already know about...
