This is what you get when the exception is propagated out of a constructor.
It breaks the abstraction, necessarily. You cannot handle this unless you
accept the idea that one can always view an object as an aggregate of other
objects. This in turn would imply 1) types matched by structure, 2) broken
encapsulation. You want the compiler to invent partial
constructors/destructors, it is a difficult problem, probably undecidable.
