@hackage lens-family-core2.1.3

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)
