Feat (Functional Enumeration of Algebraic Types) provides enumerations as functions from natural numbers to values (similar to toEnum but for any algebraic data type). This can be used for SmallCheck-style systematic testing, QuickCheck style random testing, and hybrids of the two.

The enumerators are defined in a very boilerplate manner and there is a Template Haskell script for deriving the class instance for most types. Test.Feat contain a subset of the other modules that should be sufficient for most test usage. There are some small and large example in the tar ball. Builds with haskell-platform-2012-2.0.0 and with ghc-7.6.1.
