[Python-ideas] clear() method for lists

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? -- Gerald Britton
