Generically derive traversals, lenses and prisms. This library uses GHC.Generics to derive efficient optics (traversals, lenses and prisms) for algebraic data types in a type-directed way, with a focus on good type inference and error messages when possible. The library exposes a van Laarhoven interface. For an alternative interface, supporting an opaque optic type, see generic-optics.

Infinite lists Modern lightweight library for infinite lists with fusion:
- API similar to Data.List.
- No dependencies other than base.
- Top performance, driven by fusion.
- Avoid dangerous instances like Foldable.
- Use NonEmpty where applicable.
- Use Word for indices.
- Be lazy, but not too lazy.
