Haskell is known for its clunky record syntax and common knowledge is that "lenses and prisms help", but the lens
library (the biggest player on the field) is notoriously hard to grasp (even for experienced Haskell developers). Presenting an alternative solution that is easier to work with (and has been successfully used in production) is key to encouraging newcomers to keep exploring the language, but making lives easier for existing Haskell developers.
The talk will focus on the optics
library (https://github.com/well-typed/optics).
Andrzej Rybczak will discuss:
lens
library (yet matches its power) andHe'll also discuss how optics
solves the infamous Haskell record problem in a satisfactory way (with the help of OverloadedLabels extension) and why the approach doesn't compete with the incoming RecordDotSyntax extension, but rather complements it.
