2025-04-28 01:40:30 +0200 <EvanR> well then that's not purely at the type level definitely
2025-04-28 01:39:50 +0200 <haskellbridge> <loonycyborg> I'm not so sure because of types that could be specified entirely at runtime
2025-04-28 01:39:32 +0200 <EvanR> (but I heard java erases it's types also)
2025-04-28 01:39:24 +0200mange(~user@user/mange) mange
2025-04-28 01:39:22 +0200 <EvanR> because this isn't java
2025-04-28 01:38:54 +0200 <EvanR> if it's purely at the type level then it wouldn't need to exist at runtime
2025-04-28 01:38:33 +0200 <haskellbridge> <loonycyborg> which probably will have different implementations at runtime and compile time
2025-04-28 01:38:16 +0200 <haskellbridge> <loonycyborg> still it requires operating on type level things that can't be erased
2025-04-28 01:37:20 +0200 <EvanR> erasing types or proofs shouldn't change the "observable" behavior

2025-04-28 01:36:08 +0200 <EvanR> typing with pinkies is hard
2025-04-28 01:36:02 +0200 <monochrom> Maybe the programmer doesn't use that encoding, but the compiler does the translation.
2025-04-28 01:35:56 +0200 <EvanR> if that's in the machine code then it only bothers somebody trying to disassemnle it
2025-04-28 01:35:01 +0200 <haskellbridge> <loonycyborg> Even if you technically make this work not sure it would be a good language design. Like most types that aren't passed around are erased but some have to remain which kinda feels inconsistent.
2025-04-28 01:34:21 +0200 <monochrom> :)
2025-04-28 01:34:14 +0200 <EvanR> ok yes
2025-04-28 01:32:36 +0200 <monochrom> Err, ∀r. (Πx:A. B(x) -> r) -> r
2025-04-28 01:32:13 +0200 <EvanR> ... not sure
2025-04-28 01:29:14 +0200 <monochrom> Do you accept: Encode Σx:A. B(x) as ∀r. Πx:A. B(x) -> r so it is just pi types all over again? :)

2025-04-28 01:21:18 +0200 <EvanR> sigma type is a bit more mysterious to me, how do you know someone won't want to use the 2nd component
2025-04-28 01:19:41 +0200 <EvanR> just discard the argument
2025-04-28 01:19:29 +0200 <EvanR> any call site would need to be adjusted to stop trying to call it like a function

2025-04-28 01:16:37 +0200 <EvanR> if the code doesn't use the argument, be it a type or a value, then the body is effectively a constant

2025-04-28 01:10:25 +0200 <haskellbridge> <loonycyborg> I still have no idea how can you have both pi types and type erasure in the same language.

2025-04-28 00:02:47 +0200 <davean> I have no idea if anyone has done serious work on dragging that information along though ...

2025-04-28 00:01:46 +0200 <davean> since it sorta drags providence along with it.
2025-04-28 00:00:57 +0200 <davean> I think the dependent version lets you use information a bit further away than Haskell does.
