CLC Update (May 2023)

[ChShersh]

As part of my Core Libraries Committee (CLC) involvement, I committed to writing monthly CLC updates, and this is the 3rd update.

Previous update:

• CLC Update (April 2023)

All CLC work is done by volunteers in their free time.

Featured discussion

Currently, the main and the longest discussion in CLC is about a base split, GHC internal modules in base, and how to move forward from the status quo.

All relevant discussions:

• PVP#46 | Formalize “.Internal” module convention
• HF#47 | Standard library reform: Split base
• CLC#145 | Buy-in for Technical Proposal #47
• CLC#146 | GHC-internal modules in base
• CLC#162 | base API changes introduced by GHC proposal 475

New

List of newly opened proposals since the last update.

• #156: Expose sized integer types from Prelude
• #157: Add instances for StablePtr
• #158: Make the type of (&) analogous to the one of ($)
• #160: Derive instance {Enum, Bounded, Num, Real, Integral} Compose f g a

Approved

List of approved proposals since the last update.

• #117: Export fromThreadId from GHC.Conc.Sync
• #150: Port ghcjs-base.GHCJS.Foreign.Callback as base.GHC.JS.Foreign.Callback for the GHC JavaScript Backend
• #152: Generalize the type of keepAlive#, touch#

Declined

List of rejected proposals since the last update.

It was decided not to subject issues in the array library to the CLC process:

• #103: Subject API evolution of array to CLC vote

As a consequence, a few array-related issues were closed as out-of-scope:

• #96: Add Data.Array.genArray
• #116: Add eager indexing for arrays

Withdrawn

List of proposals withdrawn voluntarily by their authors.

• #159: Automatic conversion of fixed-point representations in Data.Fixed
  • The author proposed the addition of a conversion function but an alternative already existing conversion function was suggested in replies (and the proposal itself received some pushback overall)

Abandoned or Dormant

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

None

Meta

List of CLC process updates and meta improvements.

• #155: head/tail warnings: update migration entry
  • Updated migration guide for the head/tail functions warnings
• #161: Add issue templates
  • The CLC proposal issue template was added (mostly to remind authors that they’re responsible for actually implementing the proposal)
