ISTM, the language moratorium would preclude this change.
Oops, you're right. Scratch the go-ahead. :-(
So does this mean I should bring it up again for the next round?
While PEP 3003 allows case-by-case exemptions for adding methods to built-in objects, I think this isn't one of those cases, since the work-around sure is simple enough, and has been in the language for 20 years now. ;-)
Also, since it doesn't actually add any new functionality, it is more of a documentation issue, teaching basic python idioms:
del s[:] or s[:] = []
Though it's a common-enough special case that it shouldn't need slice manipulations, which are a bit of an acquired taste. I probably would have added this if I'd anticipated dict.clear(), which wasn't always part of the language.

In the list archives, this thread
http://mail.python.org/pipermail/python-ideas/2009-April/003897.html
discusses adding a clear() method to list objects, to complement those available for sets and dictionaries. Later in the thread:
http://mail.python.org/pipermail/python-ideas/2009-April/003933.html
Christian Heimes provided a patch to do it and R. H. commented that all it would take is Guido's blessing.
So, I'm wondering, can we do this? What are the steps needed to ask this work to be blessed?
