Ghci> map.fromlist [(hello,there)] & at hello ?~ world fromlist [(hello,world)] and delete with this lens. lenses are the way to access and update parts of data structures in a pure functional way. what is provided in this library is a number of stock lenses and traversals for common haskell types, a. >>> :m + control.lens data.map.lens >>>. lens is a library for haskell that provides lenses, isomorphisms, folds, traversals, getters and setters, which exposes a uniform interface for. This package provides families of lenses, isomorphisms, folds, traversals, getters.
