(description
"This library uses @code{GHC.Generics} to derive efficient
optics (traversals, lenses and prisms) for algebraic data types in a
type-directed way, with a focus on good type inference and error messages when
possible. The library exposes a van Laarhoven interface. For an alternative
interface, supporting an opaque optic type, see @code{generic-optics}.")
