Haskell lets you write beautiful, modular code. Rather than waffle generally, I’ll use this talk to look at a particular example, Edward Kmett’s lovely lens library.

Lenses have been called “jQuery for data types”: they give you a way to poke around in the guts of some large aggregate structure. Lenses compose (so you can make big lenses by gluing together little ones), and they exploit type classes to allow a remarkable degree of flexibility (get, set, fold, traverse, etc).
