Given a lens and a value of that larger structure, two values can be dervied: a *view* value, which is the subpiece, and a *context* function, which accepts a new view value and returns a new structure with the old view replaced by the new view. Think of them as composable, pure functional getters and setters. Examples can be found in the documentation.
