Yeah, and it's alt+k on my default keyboard layout on debian… I think some punctuation is available on macos as well — so perhaps it's a windows-ism that «only AI can use punctuation».

Even more concretely, the halting problem for turing machines with halting problem oracle would be undecidable for them. And if you could solve that you won't believe what problem would be undecidable. It's turtles all the way up.

Yeah, but then you need compiler to somehow know if it's truly unreachable to know when to emit the warning and when to not do that.

Why'd 800x600 be this popular? Is this some specific device? Is this 90s? Seems suspicious to me.

Yes, but typically people are not doing this on every command and if you're globbing files it'll get used as flag.

For small separate changes in isolation then maybe it's ok? But not for whole days 8 hours each. But then you need to watch for bugs coming from interaction with previous changes and in 700k loc that might be nontrivial. How do you kno

Soundness bugs in lean are not unheard of. That's why they recommend using external checkers for "malicious" proofs. https://github.com/leanprover/lean4/issues/14576

I like the concept of separation logic as much as the next guy, but I don't think this is it. Just look at the examples, with loop invariants alone being longer than the whole example. It's not only a problem with ergonomics, but

You make relations and functions out of sets and prove theorems about them, reducing definition of things in terms of belonging to a set. This isn't particularly complicated.

It's the same way you don't need to have GCD in stdlib to say that you can compute GCD in C++. You can make your own using parts given. You don't need to add any axioms, you just build some sets to represent numbers and make
