<p>> Who said you were annoyed?<p>You did. Quote "It may annoy you,". But nevermind.<p>> You're entitled to believe that some grammatical forms are "wrong" and I'm entitled to have no respect for that opinion.<p>I think you also believe this, we only disagree in which grammatical forms. Or are you arguing that "Why waste time say lot word when few word do trick?" is grammatically correct?<p>If you are, then it is consistent with your popular-makes-correct approach as long as people say it. Whatever mistake stops being a mistake if repeated by enough people; if not, then we agree and only disagree on where the line is.<p>No bad feelings anyway. Nice chat.</p>

<p>I am not annoyed, I choose one side over the other in this debate <a href="https://en.wikipedia.org/wiki/Fewer_versus_less" rel="nofollow">https://en.wikipedia.org/wiki/Fewer_versus_less</a><p>You always have authorities like dictionaries and English usage references. There are some supporting each side of this debate in the link above.<p>> if a substantial body of people use English in a way that you dislike then it's just tough shit I'm afraid<p>There is no need for that language. hn is supposed to be a place of civil (and playful) discussion. I also already anticipated that take in my post.<p>> If instead we prefer to attribute it to class and say using the correct or wrong way is a class signifier and that both are correct, and that language depends on usage and there are no grammar rules really but only consensus, we can also do that<p>> You don't speak Elizabethan English, or Regency English, or late Saxon, or Old English, but you presumably don't think those are "wrong"<p>Because nobody actually talks like that, that's why. Joking.
You introduced the time dimension, which complicates the comparison. If somebody claimed those are all correct ways of speaking in modern English, and only class signifiers, in that context, I would say they are wrong.<p>In general I dislike this nihilist "truth does not exist" nobody-is-wrong take. That is why I prefer the simple rule with countable and uncountable without the class excuse. Ultimately both takes are valid, but I find the second one too nihilist for my taste.<p>If people one day start saying "me thinks this good" you might find yourself changing sides arguing that truth does, in fact, exist.</p>

<p>> is in practice often used by native English speakers for both count and non-count nouns<p>Alternative explanation: native speakers are wrong sometimes.<p>It really boils down to:<p>- Less + uncountable noun (money, energy, code, sand)<p>- fewer + countable noun (trees, cars, grains, volts, coins)<p>If instead we prefer to attribute it to class and say using the correct or wrong way is a class signifier and that both are correct, and that language depends on usage and there are no grammar rules really but only consensus, we can also do that. But then "Why waste time say lot word when few word do trick?".<p>I prefer the first explanation.<p>P.S. Same with "if I were" turning into "if I was". I guess usage turned that one, and that is fine too. I make that mistake often.<p>In Spanish these guys (<a href="https://www.rae.es/duda-linguistica/el-nombre-de-la-y-es-i-griega-o-ye" rel="nofollow">https://www.rae.es/duda-linguistica/el-nombre-de-la-y-es-i-g...</a>) also officially changed the name of "y" (i griega) to "ye".

<p>> having a mathlib dependency just to build a programming language is a big ask for people.<p>This is an implementation choice you did when implementing your programming language, if I understand correctly.<p>I thought of it because writing some lean lang I also had the option of adding Mathlib or keep it "bare".</p>

Also, you will be judged not only by your answer. Being so direct might show you are not on autopilot in the conversation, your humour or that you only care about money, depending on a lot of other factors. It might make one more memorable as well. I personally would read it as light humour, unless it is accompanied by a dead eyes stare.</p>

<p>IMO the solution to too many tests is to encode more things in the type system. If you can encode constraints like the length of an array in the type system you know it is correct if it compiles, and that is one less run-time test to run.</p>
