The goto is rarely used like deep break, deep continue and for handling
of non-exceptional errors (some stuff in this universe is noisy).
When people who used it knew what they do then most common attempt to
rewrite it without goto will result with bit longer and not much more
readable code and little drop in efficiency. So why to bother?

That and breaking out of nested loops.

I'm certainly not arguing that goto should see frequent use, or should
be a first choice in the vast majority of cases. Rather that if a
goto improves clarity significantly, then it's not unreasonable to use
one.
 
I was mostly trying to provide some historical context for "Goto
Statement Considered Harmful".

I've occasionally used goto in implementing state machines, which can be more
readable in this context than switch.

I thought you said you were a Christian, Scott. In fact, I called you
out on it rather staunchly previously saying that you are not saved, that
you are not a Christian.
 
If you make the claim you do above for real ... then you are lost and
have been deceived by the enemy.

Is that the other Rick, or a self parody?

So 9/11 happened not because of the actions of a group of terrorists but
because of the Big Bang because everything is connected? Of course not
because they are INDEPENDENT EVENTS. I guess you are unaware of the
concept of INDEPENDENT EVENTS. There is a model for a universe which
doesn't have INDEPENDENT EVENTS where everything is pre-ordained and
free will is an illusion but I am not convinced by it especially when
you let quantum mechanics muddy the water.

"Suppose it's all true, and you walk up to the pearly gates, and are
confronted by God," Bryne asked on his show The Meaning of Life. "What
will Stephen Fry say to him, her, or it?"
"I'd say, bone cancer in children? What's that about?" Fry replied.
"How dare you? How dare you create a world to which there is such misery
that is not our fault. It's not right, it's utterly, utterly evil."
"Why should I respect a capricious, mean-minded, stupid God who creates
a world that is so full of injustice and pain. That's what I would say."

What do you mean by flaws? What would you consider a flaw? Would you say
that there are flaws in Shakespeare, the Iliad and the Odyssey, and other
great works?
 
If you mean to suggest that there are no contradictions in the biblical texts, that's clearly not true, it was in fact the observation of contradictions that led to modern biblical scholarship.
