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
