No i want an *actual* separate instance inside the current instance
bound to an attribute "nested". But the problem is how to do this in
the constructor without causing infinite recursion. I thought about
creating an object copy function which would initialize the object and
*then* return it to the constructor but that seemed kind of kludgy.
There must be some syntax for doing this?
