Foldr type level implementation
2 projects | /r/haskellquestions | 30 Mar 2023

First class families is the approach I'm familiar with, although it can feel a bit heavy-handed. There's a chapter in Thinking with Types about how to use fcf.

Functional Semantics in Imperative Clothing (Richard Feldman)
1 project | news.ycombinator.com | 29 Apr 2024

This is really just a matter of how much syntax sugar you want to implement. Idris has this already, and there’s a proposal to add it to Haskell too [0]. But none of this changes the core properties of the system which make it monadic.

Or patterns proposal: Prefix signalling or just infix?
2 projects | /r/haskell | 17 May 2023

Additionally, while this proposal is focused on the simple implementation and so in the current proposal or patterns do not bind any variables as per #522, if we do get settled on syntax and then later wish to expand to allow binding variables as in #43, then the syntax is again clean and discoverable.
Monthly Hask Anything (May 2023)
1 project | /r/haskell | 6 May 2023

Yeah, a relatively natural thing would be to be able to opt-in to having the HasField instances be available in all contexts. The (not yet implemented, but accepted) "Modifiers" GHC proposal might be nice for that.
Is there any way to build a simple additive prelude?
1 project | /r/haskell | 1 May 2023

The local modules proposal imo is excellent as-is.
Interview and AMA with Simon Peyton Jones
1 project | /r/haskell | 22 Apr 2023

Why would you drop TypeFamilies? It seems fairly popular, given that it was just one vote short of getting added to GHC2021. Do you consider it a less-ideal compromise, that is subsumed by your second proposal (Core with GRTT)?
Amendmend proposal: Changed syntax for Or patterns
2 projects | /r/haskell | 14 Apr 2023

as syntax is contentious a topic as ever, David (the main proposal author) and I would like to invite you to give your input on https://github.com/ghc-proposals/ghc-proposals/pull/585, where we propose to change the syntax of the accepted proposal #522 introducing Or patterns. In particular, we'd like to know
MSc Dissertation: Comprehending Pure Functional Effect Systems
1 project | /r/haskell | 9 Apr 2023

This looks great, congratulations on completing it! I assume you didn’t get an opportunity to evaluate the delimited continuations based eff library? It would’ve been nice to see Cont included as one of the effects covered, though perhaps not available in all the systems you looked at? Maybe some future work.
Trouble understanding function import in Haskell

{-# WARNING #-} for Data.List.{head,tail} in future GHC 9.8
3 projects | /r/haskell | 30 Mar 2023

Right. Being able to disable "custom type warnings" at use sites was part of an earlier proposal (https://github.com/ghc-proposals/ghc-proposals/pull/454) but it ended up being shelved.
