> It should be possible to pass a {{Shared<Derived>}} value to an object that
> takes a parameter of type {{Shared<Base>}}. Similarly for {{Owned}}. In
> general, {{Shared<T2>}} should be implicitly convertable to {{Shared<T1>}}
> iff {{T2}} is implicitly convertable to {{T1}}. In C++11, this works because
> they define the appropriate conversion constructor.
