Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

An alternative front end for Haskell?
> I think Haskell needs a way to graduate (or retire) language extensions
-
Or patterns proposal: Prefix signalling or just infix?
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)
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?
The local modules proposal imo is excellent as-is.

Interview and AMA with Simon Peyton Jones
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
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
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
I do hope qualified exports are available someday: https://github.com/ghc-proposals/ghc-proposals/pull/283

{-# WARNING #-} for Data.List.{head,tail} in future GHC 9.8
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.

You may also be interested in effet, which is an mtl-like effect system which tries to overcome the limitations of mtl.

Monad Transformers and Effects with Backpack
Interesting, thank you for writing this up. I tried something very very similar before writing effet, but while working with Backpack, I was constantly questioning the ergonomics of it all (in the context of writing effects), and ultimately decided that it is not worth it and abandonded the idea.
