2021-03-14 19:18:29 <Gurkenglas> actually my gurk implementation is wrong

2021-03-14 19:23:20 Pickchea joins (~private@unaffiliated/pickchea)
2021-03-14 19:24:13 <Gurkenglas> oh, i see - gurk is impossible to implement, as it is not monotonic - i merely have that gurk x is monotonic for every x :D
2021-03-14 19:25:13 <Gurkenglas> (after all, how would it know that gurk ⊥ () is (), if ⊥ simply loops forever?)
2021-03-14 19:26:52 <Gurkenglas> (bad example, everything is less defined than (). same goes for gurk ⊥ True, though.)
2021-03-14 19:27:21 × amiri quits (~amiri@cpe-76-91-154-9.socal.res.rr.com) (Remote host closed the connection)

2021-03-14 19:28:34 <tomsmeding> > let p = (fst p, 1:snd p) in snd p -- Gurkenglas
2021-03-14 19:28:36 <lambdabot> [1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1...
2021-03-14 19:29:26 <tomsmeding> Not completely sure what you're trying to do, but maybe that helps? Fst p doesn't converge, but snd p does progress
2021-03-14 19:29:27 amiri joins (~amiri@cpe-76-91-154-9.socal.res.rr.com)
2021-03-14 19:29:30 merijn joins (~merijn@83-160-49-249.ip.xs4all.nl)
2021-03-14 19:31:59 <Gurkenglas> tomsmeding, ffgg⊥ is (2:2:⊥,1:1:⊥), ffffff... is (⊥,1:1:1:1:1:1:...). ⊥,(2:⊥,1:⊥),(2:2:⊥,1:1:⊥)(2:2:2:⊥,1:1:1:⊥),... does not converge to (⊥,1:1:1:1:1:1:...)
2021-03-14 19:32:02 carlomagno joins (~cararell@148.87.23.6)
2021-03-14 19:33:21 × Guest82 quits (97c9916a@gateway/web/cgi-irc/kiwiirc.com/ip.151.201.145.106) (Quit: Connection closed)
2021-03-14 19:33:45 <hpc> ffffff...gggggg... is fffff... though
2021-03-14 19:34:31 <Gurkenglas> hpc, and yet the values of the terms are not the same
2021-03-14 19:35:22 <Gurkenglas> which is concerning, as i thought as you did
2021-03-14 19:35:49 <hpc> sure they are, fffff...gggggg... converges to (⊥,1:1:1:1:1:1:...) because it can never reach the gs
2021-03-14 19:36:00 <hpc> fgfg... is different
2021-03-14 19:36:13 × Sornaensis quits (~Sornaensi@077213203030.dynamic.telenor.dk) (Ping timeout: 260 seconds)
2021-03-14 19:36:22 <hpc> things get weird at the limit
2021-03-14 19:37:58 × notzmv quits (~zmv@unaffiliated/zmv) (Ping timeout: 245 seconds)
2021-03-14 19:37:59 <Gurkenglas> ah, I meant "and yet, the value that the sequence converges to is not the same as the value of the infinitary term"
2021-03-14 19:39:32 × rayyyy quits (~nanoz@gateway/tor-sasl/nanoz) (Ping timeout: 268 seconds)
2021-03-14 19:39:47 <monochrom> I don't know what "fff...ggg..." means.
2021-03-14 19:39:59 <Gurkenglas> i had hoped that, in general, the mapping from terms to values would be continuous. now that i think about it in those terms, there's a simpler counterexample: id^n(True)
2021-03-14 19:40:04 × sparsity quits (5ce955fb@gateway/web/cgi-irc/kiwiirc.com/ip.92.233.85.251) (Quit: Connection closed)
2021-03-14 19:40:25 <Gurkenglas> monochrom, "f(f(f(...g(g(g(...", which is just "f(f(f(..." of course
2021-03-14 19:40:28 <monochrom> There was once a 0.999...=1 denier I saw on the Internet
2021-03-14 19:40:54 <hpc> ppsh, everyone knows 0.999...=-1/12
2021-03-14 19:40:55 <monochrom> Their denial reason was "0.999... = 0.999...9 it ends with 9".
2021-03-14 19:41:08 <monochrom> That's the same flaw as "fff...ggg..."
2021-03-14 19:41:26 <Gurkenglas> (or rather, one can define infinitary terms but once you map it to values everything from omega onwards is cut off)
2021-03-14 19:42:13 <tomsmeding> iterate (. f) f . iterate (. g) g
2021-03-14 19:42:51 <tomsmeding> Ah that makes no sense
2021-03-14 19:43:02 <Gurkenglas> fix (f.) . fix (g.)
2021-03-14 19:43:02 <hpc> hmm
2021-03-14 19:43:17 <tomsmeding> :t \f g -> fix f . fix g
2021-03-14 19:43:19 <lambdabot> ((b -> c) -> b -> c) -> ((a -> b) -> a -> b) -> a -> c
2021-03-14 19:43:20 × Franciman quits (~francesco@host-82-49-79-189.retail.telecomitalia.it) (Quit: Leaving)
2021-03-14 19:43:33 <hpc> fix (f .) . fix (g .) /= fix ((f .) . (g .))
2021-03-14 19:43:41 <Gurkenglas> :t \f g -> fix (f.) . fix (g.)
2021-03-14 19:43:42 <lambdabot> (c -> c) -> (a1 -> a1) -> a2 -> c
2021-03-14 19:43:59 <hpc> so i guess the compact way to phrase it is "function composition and fixed points don't distribute"
2021-03-14 19:43:59 <tomsmeding> Lol that inferred type
2021-03-14 19:44:18 <Gurkenglas> hpc, "denotation isn't continuous"
2021-03-14 19:44:37 kiweun joins (~kiweun@2607:fea8:2a62:9600:40c1:4e90:a63c:4a65)
2021-03-14 19:45:20 <monochrom> https://mail.haskell.org/pipermail/haskell-cafe/2011-January/088315.html
2021-03-14 19:45:25 <monochrom> "detonational semantics"
2021-03-14 19:45:32 <Gurkenglas> tomsmeding, it's saying that the types don't need to agree because the plumbing never actually connects :)

2021-03-14 19:48:50 <monochrom> and "zen semantics", that one is a great ending.
