lens-family-core-2.1.2: Haskell 2022 Lens Families

This package provides first class(†) functional references in Van Laarhoven style supporting the following optics:

• Lenses (view, over)
• Traversals (toListOf, matching, over)
• Setters (over)
• Grates (zipWithOf, under, review)
• Resetters (under)
• Adapters (view, review)
• Grids (toListOf, over / under, review)
• Prisms (matching, over / under, review)
• Getters (view)
• Folders (toListOf)
• Reviewers (review)

(†) For optimal first-class support use the lens-family package with rank 2 / rank N polymorphism. Lens.Family.Clone allows for first-class support of lenses and traversals for those who cannot support rank 2 polymorphism.
