CLC Update (March 2023)

[ChShersh]

I would like to start publishing monthly Core Libraries Committee (CLC) digests to increase transparency and visibility around CLC.

This is my personal initiative but all other CLC members are welcome to join and publish updates as well if they’re willing to

CLC is governed by volunteers and the work is done in free time.

Abandoned

List of abandoned proposals due to lack of progress from the proposal author.

• Add quantified superclasses to Bifoldable and Bitraversable · Issue #93 · haskell/core-libraries-committee · GitHub

Meta

List of CLC processes updates and meta improvements.

• Write expectations from the proposal author explicitly by chshersh · Pull Request #137 · haskell/core-libraries-committee · GitHub
  • I (@chshersh) opened a pull-request with documentation changes to elaborate on expectations from proposal authors. The PR has some feedback, and I’ll update my changes accordingly when I have the opportunity to do so.
• Impact assement of breakage caused by mtl-2.3 · Issue #136 · haskell/core-libraries-committee · GitHub
  • mtl-2.3 introduced a significant breaking a change and a discussion with CLC was raised to see who will take the responsibility for this change
• Should every member provide a manifesto? · Issue #141 · haskell/core-libraries-committee · GitHub
  • In an attempt to give proposal authors an idea of how likely their proposals will be accepted or rejected, a discussion was raised with the idea that every CLC member writes a manifesto sharing their personal values and vision of changes in base. The discussion was closed with no follow-up action to being derailed into other directions and some pushback towards the original idea.

• Restrict the type of `Data.List.NonEmpty.unzip` · Issue #86 · haskell/core-libraries-committee · GitHub
