The compdata-param package

[Tags: bsd3, library]

Based on Wouter Swierstra's Functional Pearl Data types a la carte (Journal of Functional Programming, 18(4):423-436, 2008,, this package provides a framework for defining recursive data types in a compositional manner with support for binders.

This package implemements parametric compositional data types (Workshop on Mathematically Structured Functional Programming, 3-24, 2012,, generalising compositional data types (as implemented in the compdata package) with support for parametric higher-order abstract syntax (PHOAS).

Examples of using parametric compositional data types are bundled with the package in the folder examples.
