Data types as fixpoints http://www.cse.unsw.edu.au/~rl/code/fixpoint.html

This package is not currently in any snapshots. If you're interested in using it, we recommend adding it to Stackage Nightly. Doing so will make builds more reliable, and allow stackage.org to host generated Haddocks.
This package allows data types to be seen and manipulated as fixpoints of their underlying functors. It is mostly based on "Functional Programming with Bananas, Lenses, Envelopes and Barbed Wire" by Erik Meijer, Maarten Fokkinga and Ross Paterson (http://citeseer.ist.psu.edu/meijer91functional.html). It makes essential use of associated types and related extensions.
