Backwards-compatible orphan instances for base

base-orphans Hackage version Build Status

Scope

base-orphans defines orphan instances that mimic instances available in later versions of base to a wider (older) range of compilers. base-orphans does not export anything except the orphan instances themselves and complements base-compat.

Usage

To use base-orphans, simply import Data.Orphans ().
