A library to support the definition of generic functions. Datatypes are viewed in a uniform, structured way: the choice between constructors is represented using an n-ary sum, and the arguments of each constructor are represented using an n-ary product.

The module Generics.SOP is the main module of this library and contains more detailed documentation.

Examples of using this library are provided by the following packages:

A detailed description of the ideas behind this library is provided by the paper:
