Wow, someone actually suggested that?! Do people write whole programs like this?
Unfortunately, short names do not indicate that someone did know what they were doing! =)
In reality, of course, software development is about getting large groups of people in-sync as to problem, solution, and implementation. That takes lots and lots of communication. Ambiguous, messy people-to-people stuff, without The Right Solution to contents or wording. Because there's a bias towards thinking of the Program as Reality, it never occurs to such developers that an identifier can become just as outdated or wrong as a comment, and in fact it is easier to correct a comment than to globally rename identifiers, or that a 20-word comment carries vastly more information and nuance than a 20-character function name, or that trying to shoehorn information important to developers into a language used to tell _computers_ how to function is worse than trying to drop assembly language into a SQL query.
I realize you're trying to explain a way of thinking that you don't actually share—but this doesn't make sense to me either.
Computers parse identifiers in only the simplest sense—they care if two identifiers are identical to each other or different. So, any identifier longer than one or two characters is in some sense a comment, because everything longer the minimum necessary to make the identifier unique is ignored. They're literally stripped from the output if you don't retain debug symbols or use a minifier (depending on the type of language).
To me, the suggestion seems so incredibly bad that it leaves me wondering about the headspace of someone who would suggest that. Is it somehow less bad than it seems?
