There cannot possibly exist any D mine or anyone else's that

No D that anyone in the universe can define can simultaneously be
the caller of a function and the input to the same function.
If you think that it can then provide such a D.

I mean... yes, it is?

 
No you are wrong.

Please clarify. Does "DDD" refer to two different programs?

DDD correctly simulated by HHH cannot possibly reach its own simulated
"return" statement final halt state.

DDD doesn't reach anything, HHH does (or doesn't). By nature no simulator
can simulate itself.

Also this is the third time in a row that I have to ask why you don't
respond to my full post.

Unless your execution environment allows assigning different things the
same name, DDD refers to exactly one function at one address. Why don't
you say that you mean the specific invocation at this point in the call
stack?
 
And what about the rest of my reply above and what you snipped?
