No-one in the linked thread seemed to know why .destroy is used
in nullify. Looki

Only nullify() can make isNull return true again. I need that
semantic.

Quick idea without much afterthought: instead of Nullable, use
pointer to o?

I've been bitten by trying to use Nullable(T) on class types.
Minimal example...
import std.typecons : Nullable;

o.toString();
n.nullify();
o.toString(); // SegV!
}
The SEGV is caused by nullify
