type-level-natural-number: Simple, Haskell 2010-compatible type level natural numbers

[ bsd3, data, library, type-system ] [ Propose Tags ]

This is a simple, Haskell 2010 compatible implementation of type-level natural numbers. Operations requiring non-Haskell 2010 language extensions have been split into a separate package.

The difference between this package and the many others on Hackage implementing type-level naturals is its emphasis on simplicity. It only supports non-negative natural numbers, and only the successor and predicessor operations. It represents natural numbers using a type-level linked list, so it is not intended to be used for representing large numbers. Pre-defined aliases for natural numbers up to 15 are provided.

The code for this package was largely taken from the excellent Vec package; I created this package with the intent of making this functionality more widely available.

Difference from 1.0: Added instances for Typeable, and word synonyms for N0...N15.
