I think that should work. The constructor does not initialize the fields, it's
done before the constructor is called. This works:

extern (C) Object _d_newclass(in ClassInfo);

class Room
{
    int i = 3;

    this (int f) {}
}

void main ()
{
    auto room = cast(Room) _d_newclass(Room.classinfo);
    assert(room.i == 3);
}

The constructor is not called but the field is initialized anyway.
