I want a way to default initialize a class variable to a default object (e.g. by wrapping it in a struct, because initialization to null cannot be changed directly). Such a default object is of course not available at compile time which seems to make this impossible. Can this be done in some way?

You can construct objects at compile time.

If I understand your question properly:

```d
struct Wrapper
{
   Object x = new Object();
   alias x this;
}

void foo(Object o)
{
   assert(o !is null);
}

void main()
{
   Wrapper w;
   foo(w);
}
```
