FYI, in case you missed it the final version doesn't need a Proxy base
class, just inherit from object. Also lowercased ProxyMethod to look
similar to staticmethod/classmethod:

class A(object):

    def __init__(self, b1, b2):
        self.b1 = b1
        self.b2 = b2

    @proxymethod
    def bmethod(self):
        return self.b1

    @proxymethod
    def bmethod2(self):
        return self.b2
