What blog?

To spell it out for you, very slowly: Casing is locale-sensitive.

You cannot determine whether file A and file B have the same case without taking the language the filename was written in into account.

Which means you need to somehow attach the locale to every file (name). Your browser could implement something to add that (semi-)automatically, but if grandma is creating a file from scratch, there is only so much you can do.

I hope this helps you understand why the thing you propose is stupid.

Why do have such a strong opinion on things you –rather obviously– understand very poorly?

Why would grandma need to specifiy the locale?

Yeah, maybe figure this one out for yourself to get you on track for learning something.

someone spontaneously brings up non-latin alphabets as if they are equivalent to case sensitivity for no good reason

That sentence makes no sense. You don't have to agree on things, but at least be coherent in your objection.

Good catch, that should have been if person in the first line.

It's been a left-over from when syntax looked like this:

  is Person("Alice", _)$person then "{$person.age}"
  is Person("Bob", $age)       then "$age"

So every time grandma picks a file name she needs to specify the locale?

What a stupid hill to die on.

How would that happen?
