Alias for an attribute defined in a superclass

Howdy all,

I want to inherit from a class, and define aliases for many of its
attributes. How can I refer to “the attribute that will be available by
name ‘spam’ once this class is defined”?

    class Foo(object):
        def spam(self):
            pass

        def eggs(self):
            pass

    class Bar(Foo):
        beans = Foo.spam
        mash = Foo.eggs

Is that the right way to do it? Will that leave me open to “unbound
method” or “is not an instance of ‘Bar’” or other problems when using
‘Bar.beans’?
