Oh... one other thing that would be really cool is to do this with AOP/
descriptors!  I just haven't been able to get that to work either.
Basics...

@readonly
class MyClass(object):
        def __init__(self, x):
                self.set_x(x)

        def get_x(self):
                return self.__x

        def set_x(self, x):
                print 'Hello the setter was called!'
                self.__x = x

and it's done!  I don't think this will work because (maybe I'm wrong)
but I don't think you can set the metaclass in the descriptor???  If
this is the case, it is more work to do the AOP and set a metaclass...
better to just inherit.  If it can be done... that would be awesome!
