| 2025-02-12 20:45:07 +0100 | <hololeap> | I guess now I need to learn how to use SelectT |
| 2025-02-12 20:41:58 +0100 | <hololeap> | both of those transformers were annoying to work with without mtl support |
| 2025-02-12 20:41:36 +0100 | <hololeap> | that and Control.Monad.Accum are excellent additions |
| 2025-02-12 20:40:00 +0100 | <tomsmeding> | huh |
| 2025-02-12 20:39:58 +0100 | <tomsmeding> | it's not |
| 2025-02-12 20:39:46 +0100 | <hololeap> | Control.Monad.Writer.CPS Since: mtl-2.3, transformers-0.5.6 |
| 2025-02-12 20:39:46 +0100 | <tomsmeding> | 2019 for transformers and 2022 for mtl? That feels wrong |
| 2025-02-12 20:39:32 +0100 | <tomsmeding> | oh it hasn't? |
| 2025-02-12 20:39:15 +0100 | <tomsmeding> | that has been there for ages :) |

| 2025-02-12 20:37:30 +0100 | <hololeap> | glad to see mtl-2.3 has CPS writer support |

| 2025-02-12 20:35:46 +0100 | <hololeap> | ok |
| 2025-02-12 20:34:57 +0100 | <c_wraith> | you could get the "previous" w, but you wouldn't see any changes made in the action at the scope you're catching |
| 2025-02-12 20:33:37 +0100 | <hololeap> | fwiw I was using the CPS WriterT, but I assume it would also lose w |
| 2025-02-12 20:31:14 +0100 | <c_wraith> | the non-CPS WriterT is terrible and probably never should be used. |
| 2025-02-12 20:30:40 +0100 | <c_wraith> | but w isn't going to be around |
| 2025-02-12 20:30:17 +0100 | <c_wraith> | You can catch in that type |
| 2025-02-12 20:30:09 +0100 | <lambdabot> | IO (a, w) |
| 2025-02-12 20:30:09 +0100 | <c_wraith> | @unmtl WriterT w IO a |
| 2025-02-12 20:28:49 +0100 | <hololeap> | (I'll probably end up using Reader+IORef, but I'm curious if this is possible) |
| 2025-02-12 20:28:07 +0100 | <hololeap> | it's in a loop using `execWriterT $ forM_ ...` |
| 2025-02-12 20:27:22 +0100 | <hololeap> | with `WriterT w IO`, is it possible to catch ctrl+c and dump the `w` stdout before aborting, or do I require `ReaderT (IORef w) IO` |

| 2025-02-12 20:13:26 +0100 | <mauke> | I figured there would be some kind of diagonalization involved |
| 2025-02-12 20:10:10 +0100 | <monochrom> | But I have proved that the infinite stream monad is unique (and its <*> does zipping). join xss = [xss !! n !! n | n <- [0..]] |

| 2025-02-12 20:06:07 +0100 | <monochrom> | Yes, moreover you have to ban all finite lists. |
| 2025-02-12 20:05:57 +0100 | <lambdabot> | ZipList {getZipList = [42,42,42,42,42,42,42,42,42,42,42,42,42,42,42,42,42,42... |
| 2025-02-12 20:05:56 +0100 | <mauke> | > pure 42 :: ZipList Int |
| 2025-02-12 20:05:48 +0100 | <geekosaur> | iirc ZipList would require `return` to produce an infinite list? |
| 2025-02-12 20:05:41 +0100 | <monochrom> | But I came close to seeing why ZipList cannot be a monad. |
| 2025-02-12 20:03:51 +0100 | <monochrom> | I don't actually know of one. I made a bet. :) |
| 2025-02-12 20:01:55 +0100 | <mauke> | is there a simple proof that Monad [] is unique? |
| 2025-02-12 20:00:48 +0100 | <lambdabot> | ZipList {getZipList = [10,21]} |
