# 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:

```bash
nix develop
cabal run
cabal test

nix build
./result/bin/mini-deriving

nix run
nix flake check
```
