I posted the same thing to python-dev (although it took a week for the 
post to appear) and some guy said -infinity or something smart like that.
I think it is simpler to use keywords for classmethod and staticmethod 
at least.  Those are builtin features of python, just like they are 
builtins for java (which has keywords for its builtins like static, 
abstract, interface, etc.).
I propose this *in addition* to whatever decorator syntax we add.  We 
shouldn't consider staticmethod and classmethod as decorators.
