Well, a dynamic array of pointers, but the situation is the same.

I don't know. I don't know enough about compilers.

To see what I can see. And terminate this little dance.
If that's not possible, then I'd like to have a syntax to give the necessary hint to the (less than smart) compiler. For example saying the size of one or both structs.
This was just an example, but it's not the first time I fall in this problem when I create data structures in D.
Bye and thank you,
