When compiling this with rdmd I get the message: "Error: this for c needs to be type A not type B". Is there a way to call c from d?

Now I found this: https://forum.dlang.org/thread/eobdqkkczquxoepsteue@forum.dlang.org

Seems to be intentional, that this doesn't work. In my case I'm able to move d() into the outer struct...

You'll need a pointer to the outer struct, or run it in an function where it then passes a pointer of data that's seen in the scope i believe.
