September Virtual CoHack Recap

  • We had 12 people in attendance overall, ranging from experienced Haskell programmers to the novice and intermediate level. We had a great time getting to know each other and hearing each other’s Haskell stories.
  • One group worked on getting started with the implementation of the lambda cases GHC proposal. They made significant progress on lexing and parsing work to implement the feature.
  • Another group worked on explainable-predicates, implementing a number of minor feature requests and culminating in the implementation of qADT, a powerful Template Haskell combinator for convenient matching of algebraic data types with predicates for the fields. A new version has been released.
  • Yet another group worked on documentation for Data.Foldable, focusing on making the documentation more precise, accessible, and helpful with examples and clear language.
