September Virtual CoHack Recap

The September chapter of the Virtual Haskell CoHack is now past. Here’s how it went:

• 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.

We’ve already got the next Virtual Haskell CoHack scheduled, so go ahead and sign up if you’d like to join the fun next time around.
