2026-04-22 18:41:25 +0000 <monochrom> Personally I just fight bottom mistakes with test cases. This is more powerful in Haskell than in many other languages. Due to parametricity, if a sufficiently polymorphic function terminates for one test, then it terminates for a large generality.
2026-04-22 18:38:44 +0000 <gentauro> must try again I guess
2026-04-22 18:38:38 +0000 <gentauro> I tried to use it, couldn't make it build (nightly though)
2026-04-22 18:36:32 +0000 <monochrom> But I have a feeling that Liquid Haskell is even less widely used than Lean.
2026-04-22 18:36:03 +0000 <monochrom> I guess yes.
2026-04-22 18:35:39 +0000 <gentauro> monochrom: can you ban `bottom` with Liquid Haskell comments?

2026-04-22 18:01:22 +0000 <monochrom> When I took a compiler course, I submitted as a test case the Ackermann function! (The prof gave bonus marks for supporting recursion.)

2026-04-22 17:54:23 +0000 <monochrom> Yeah my thesis supervisor is like "termination is uninformative" because of that.
2026-04-22 17:53:51 +0000 <int-e> monochrom: if it can implement the Ackermann function, is it really terminating ;)
2026-04-22 17:52:49 +0000 <monochrom> (unless the talker actually advocates going all out for those two)
2026-04-22 17:52:06 +0000 <monochrom> For now, IMO banning bottoms is just a lot of high-horse unpragmatic talk.
2026-04-22 17:51:32 +0000 <monochrom> To be sure, I would be happy if someone found a third way much more ergonomic than those two.
2026-04-22 17:50:50 +0000 <monochrom> (Belated) If one wants to ban bottoms, the only two currently widely deployed ways are System F (eg Dhall) and dependent type theory (eg Agda, Lean).
