LLMs do not reason at all (i.e. deductive reasoning using a formal system). Chain of thought etc simulate reasoning by smoothing out the path to target tokens by adding shorter stops on the way.

That being true does not mean that there are no limits to whatever it might be doing, which might be wasted with ambiguous naming schemes.

I am far from an AI booster or power user but in my experience, I get much better results with descriptive identifier names.

LLMs are only capable of performing a finite amount of computation within a single forward pass. We know that much.

They are also known to operate on high level abstracts and concepts - unlike systems operating strictly on formal logic, and very much like humans.
