Template Haskell utilities for the data-effects library.

TemplateHaskell functions for deriving effect invocation functions, HFunctor instances, and more from the definition of effects with data-effects-based GADT representations.

data-effects

A basic framework for a Haskell effect system library based on GADTs-based effect representations with a style that separates first-order effects and higher-order effects.

This library set was created by being separated from the Heftia extensible effects library.
