[T]his package provides a framework for defining recursive data types in a compositional manner. The fundamental idea of compositional data types is to separate the signature of a data type from the fixed point construction that produces its recursive structure. By allowing to compose and decompose signatures, compositional data types enable to combine data types in a flexible way. The key point of Wouter Swierstra's original work is to define functions on compositional data types in a compositional manner as well by leveraging Haskell's type class machinery.

Building on that foundation, this library provides additional extensions and (run-time) optimisations which make compositional data types usable for practical implementations. In particular, it provides an excellent framework for manipulating and analysing abstract syntax trees in a type-safe manner. Thus, it is perfectly suited for programming language implementations, especially, in an environment consisting of a family of tightly interwoven domain-specific languages.

In concrete terms, this package provides the following features:
