How to get access to Voldemort / private thingies

[Johan Engelen via Digitalmars-d-learn]

Hi all,
  Is there another way to get access to Voldemort class methods, 
or private class members, other than using "pragma(mangle, ...)" 
on user symbols?

Example code:

In library, and _should not_ be changed :
```
Object getObject() {
    class Vold : Object {
        int store;
        this(int i) {
           store = i;
        }
    }
    return new Vold(2);
}

class Thread
{
     private:
     static struct AAA
     {
          int i;
     }
    __gshared AAA*  sm_cbeg;
}
```

And then the code seeking access:
```
pragma(mangle, "mangled name of Vold's constructor")
    private extern(C) void defaultTraceInfoCtor(Object) @nogc;

struct A
{
    int i;
}
__gshared extern {
    pragma(mangle, "the mangled symbol name") A* sm_cbeg;
}
```

Go mad on the "code seeking access" :-) The problem is that the 
types of `defaultTraceInfoCtor` and `sm_cbeg` are incorrect. If I 
can get the types to match (internally in the compiler), I'm 
happy.

Thanks,
  Johan
