"Scrap your boilerplate" --- Generic programming in Haskell See http://www.cs.vu.nl/boilerplate/. The present module contains thirteen Data instances which are considered dubious (either because the types are abstract or just not meant to be traversed). Instances in this module might change or disappear in future releases of this package.

(This module does not export anything. It really just defines instances.)
