It actually depends on when you instantinate scoped_ptr's dtor. It is likely
that dtor for it won't be instantinated before dtor of "handle' and
therefore, before handle's first creation. And since ctor of handle is likely
to create body it will require struct body to be complete type.
I agree that it is possible to make wrong thing unintentionally, though.

As I have stated in previous post, with sizeof(T):
