24-haskell-deriving

This example shows intermediate Haskell deriving with stock and newtype strategies.

It includes:

• deriving stock for ordering, enumeration, and display,
• GeneralizedNewtypeDeriving for numeric and semigroup behavior,
• one release batch that merges and sorts targets through derived instances, and
• a test suite run by nix flake check.

Useful commands:

nix develop
cabal run
cabal test

nix build
./result/bin/mini-deriving

nix run
nix flake check
