2024-12-22 19:32:09 +0100 <monochrom> If you do use call/cc aka Pierce's law to extend Curry-Howard, then excluded middle executes like this story: https://www.cs.cmu.edu/~cmartens/if/dem.html#4.8 >:)

2024-12-22 19:22:04 +0100 <albet70> monochrom , Pierce's law is related to Yoneda embedding?

2024-12-22 19:18:02 +0100 <monochrom> Although, when you instead look for extending Curry-Howard to classical logic, call/cc is Pierce's law and is exactly the one single thing you need to complete classical logic.

2024-12-22 19:13:30 +0100 <albet70> monochrom , callCC can capture the rest code which is after it?
2024-12-22 19:12:55 +0100 <monochrom> And Python's yield corresponds to shift-reset rather than call/cc. https://www.cs.indiana.edu/~sabry/papers/yield.pdf
2024-12-22 19:11:47 +0100 <albet70> is that redis distributed lock very like MVar?

2024-12-22 19:11:02 +0100 <monochrom> As Oleg points out, call/cc is not very nice. shift-reset is better. Even the Haskell Cont library provides shift-reset.
2024-12-22 19:10:06 +0100 <monochrom> Whereas with shift-reset you really always have multiple levels.
2024-12-22 19:09:43 +0100 <monochrom> Of course you get to say "but only within runCont" but it is not like you really have multiple levels of runCont.

2024-12-22 19:09:12 +0100 <monochrom> callCC is global because there is no reset to scope it.

2024-12-22 18:57:27 +0100 <albet70> can I say callCC is delimited continuation and call/cc is full contit?

2024-12-22 18:45:24 +0100 <ski> evalCont ca = ca `runCont` id -- `id' here is the initial ("empty") delimited/composable continuation
2024-12-22 18:44:36 +0100 <probie> ski: That sounds like a fun challenge. I think I'll have a go
2024-12-22 18:42:33 +0100 <albet70> ski , what's the delimited continuation
2024-12-22 18:41:51 +0100 <albet70> enikar , but call/cc still in r4rs?
2024-12-22 18:41:42 +0100 <ski> (albet70 : and no recursive computation needed/permitted, apart from the one inside `foldr')

2024-12-22 18:38:44 +0100 <ski> `callCC' is delimited by the `runCont'/`runContT', yes

2024-12-22 18:38:00 +0100 <ski> albet70 : the challenge was to implement `zipWith' (or `zip', if you prefer), only traversing either input list (and only once), with a single call to `foldr' for each, not inspecting the lists in any way apart from that
