What "Turkish schools" call it is irrelevant, it adds "colour" to an event. Just because the events happen to be in the past, does not make the Inferential Mood a tense. An event can be in the past but factual.
Wouldn’t Turkish schools know more what their language’s rules and meaning is better than Hacker News?
Yes they do, because schoolteachers don't each invent their linguistic terminology as they go along in isolation, it's done by some regulatory governing body. Something like https://en.wikipedia.org/wiki/Turkish_Language_Association. If anything, that's more centralized and controlled than what our countries have. So then it's not between the word of linguists on HN and some random primary school teacher in Turkey, but between the Turkish linguists deciding about their language and HN linguists.
And I am sure HN linguists think they know all the languages (programming or otherwise) better than anyone else, but somehow I doubt that.
In elementary school in Canada, I was taught phonetics to help learn sounding words out. This was absolutely a government-sanctioned curriculum. I was taught that the sounds are categorized as either consonants or vowels. Every English speaker can confirm that of course this is correct.
But then you major in linguistics and discover that the elementary school definition of consonants and vowels is actually not quite right. And you can’t even categorize certain sounds well (such as the “w” in “we”, which is actually pronounced with a mostly open vocal tract).
Studying linguistics is already confusing because the boundaries between morphology, syntax, semantics and pragmatics are not so clear in the first place, so getting rid of any ambiguity is important to linguists, but those things aren’t important to people who simply study the language to speak it.
