Yup.  It seems to me that there are a number of different use cases
and they all want to try to use the same new syntax.

That's possible without new syntax.  Some example code:

    import sys

    def myclassmethod(func):
        frame = sys._getframe(1)
        name = func.func_name
        if name in frame.f_locals:
            namespace = frame.f_locals
        elif name in frame.f_globals:
            namespace = frame.f_globals
        else:
            raise NameError, 'cannot find %r' % name
        namespace[name] = classmethod(func)

    class A:
        def something():
            pass
        myclassmethod(something)
        print something

It's not pretty but it might prevent people from developing RSI
while Guido works out what new syntax is best.

That's true.
