Uhm. That won't work with the GC…
It won't work with the GC, but one could still safely implement
an XOR linked list in D, if they used malloc/free manually, so
that the collector was never aware of the existence of those
allocations.
As to the OP, at the moment, D doesn't support structs as a
reference type so if you want a container that stores references
to structs rather than copies, the container will probably use
pointers.
