The Effekt language blog presents an innovative approach to recursion schemes using effects and handlers instead of traditional functor-based implementations. This demonstrates how algebraic effects can refunctionalize data structures and simplify recursive traversals. The interactive post includes practical code examples for implementing catamorphisms on lambda calculus terms.
Background
Recursion schemes are well-established patterns in functional programming for abstracting recursive operations like folds and unfolds. Traditional implementations rely on functors and recursive types.
