As Matthias Lang mentioned, keeping a reference to itself makes
a struct object illegal in D. D sees structs as value types: It
is supposed that any copy can be used in place of another copy.

Ali,
You highlight am important point that I have not been completely
aware of.
Indeed, I did have a few "warning bells" going off in my brain
when I began
typing "this.myadd = &this;" into my program ... but, it
compiled, so I
continued (into the potential quicksand, admittedly!)
So, thanks for illuminating this issue for me.
Also, the "postblit" hint recently posted in this thread, may
allow me
to procede along a safer path.
Kind Regards,
James
