Helps Haskell developers adopt and consistently apply the Effectful library conventions across projects, reducing boilerplate and errors when composing effects.
Set up a minimal Effectful program using Reader, State, and IOE, then run it to verify correct composition.

To compose Haskell effects, apply Effectful library conventions for static and dynamic dispatch. This standardizes how Reader, State, Error, and IOE effects interact, ensuring modular interpreters and composable handlers across your workflows.
Migrating MTL-style code to Effectful patterns involves aligning existing typeclasses with Effectful's effect composition. This transition enables per-function error scopes and composable handlers while reducing boilerplate and errors in your Haskell project.
Defining custom effects involves creating new effect types and building corresponding interpreters. You can test these custom effects by constructing mock handlers to validate behavior and ensure testable, composable effect execution.
Yes, Effectful supports dynamic dispatch and per-constructor error constraints. This allows you to design modular interpreters and manage per-function error scopes effectively across common Haskell workflows.
Set up a minimal Effectful program by combining Reader, State, and IOE effects, then run it to verify correct composition. This quick start approach validates that your effect handlers interact as expected within the Haskell application.
