The problem is the compiler has to assume you *might* be linking 
to opaque .o files, so it can't provide any introspection 
capabilities. There's no way to tell which "hidden type" that the 
getObject function is returning, since that's decided in the 
(possibly opaque) function body.

You could hack something with debugging, I suppose. (Probably 
not. DWARF/ptrace is ridiculously undocumented.) Perhaps you 
could make an alternate version of the function with the same 
source code, that returns auto instead of an Object type? As in...

Object evil() {
   class Vold {...}
   Vold v = new Vold(...);
   return v;
}


auto notevil() {
   static class Vold {...}
   Vold v = new Vold(...);
   return v;
}

...

auto hack = new typeof(notevil());

That can magically allow you to return type Vold, even though 
it's an error to say

Vold notevil() {
   static class Vold { ... }
   ...
}
