Replace "self" with "me".

I don't see why you think this is a problem. The compiler merely treats:

    def ANYTHING.method(arg):

inside a class as if it were 

    def method(ANYTHING, arg):


and it will Just Work. If you want a classmethod, you still need to use 
the classmethod decorator -- there's no reason to make self and cls 
keywords.

Personally, I'm neutral on the idea. Perhaps +0.00001.
