Heftia is an extensible effects library for Haskell that generalizes "Algebraic Effects and Handlers" to higher-order effects, providing users with maximum flexibility and delivering standard and reasonable speed. Heftia is an extensible effects library for Haskell that generalizes "Algebraic Effects and Handlers" to higher-order effects, providing users with maximum flexibility and delivering standard and reasonable speed.
In its generalization, the focus is on ensuring predictable results based on simple, consistent semantics, while preserving soundness. In its generalization, the focus is on ensuring predictable results based on simple, consistent semantics, while preserving soundness.
