Dotted names would be sufficient rather than general lvalues.

I like this, I think it looks cleaner than the other options, especially if 
you write both getter and setter in the same style:

    attribute = property()

    def attribute.fget(self):
        return 42

    def attribute.fset(self, value):
        self._ignored = value
