Though, more to the point:
I would probably forbid "Foo foo = new Foo(this);". The design that

Circular object references are often justified.
Would we lose much of value?
Well this would amount to forbidding escaping an object from its
constructor, as well as forbidding calling any member functions from the
constructor. Also, if you *need* to create a circular structure, you'd
have to use sentinel objects. Those are worse than null.
OK, that does sound unusually harsh.
