What about `this(int = 0)` class constructor?

And, with v2.064-devel-64d739f, C.s is still assigned from a temporary object
instead of being constructed directly. That defeats the purpose of " disable
this", because assignment assumes that the target object has been properly
constructed. And, in the presence of " disable this", "set to init" does not
qualify for "properly constructed".
