typedef int (*ptr)();  // ptr is pointer to int function in C
00       int H(ptr p, ptr i);
01       int D(ptr p)
02       {
03         int Halt_Status = H(p, p);
04         if (Halt_Status)
05           HERE: goto HERE;
06         return Halt_Status;
07       }
08
09       int main()
10       {
11         H(D,D);
12         return 0;
13       }

The above template refers to an infinite set of H/D pairs where D is
correctly simulated by either pure simulator H or pure function H. This
was done because many reviewers used the shell game ploy to endlessly
switch which H/D pair was being referred to.

H correctly simulates 1 to ∞ steps of D with either pure function H or
pure simulator H. In none of these cases does the correctly simulated D
ever reach its own simulated final state and halt.

*In actual finite memory C the H/D pair would eventually crash*

*Correct Simulation Defined*
    This is provided because many reviewers had a different notion of
    correct simulation that diverges from this notion.

    A simulator is an x86 emulator that correctly emulates 1 to N of the
    x86 instructions of D in the order specified by the x86 instructions
    of D. This may include M recursive emulations of H emulating itself
    emulating D.

*Fully operational code proves recursive emulation*

When we see that D correctly simulated by pure simulator H would remain
stuck in infinite recursive simulation then we also know that less than
an infinite number of steps is not enough steps for D correctly
simulated by pure function H to reach its own simulated final state at
line 06 and halt.
