base-orphans

Backwards-compatible orphan instances for base.

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 <http://hackage.haskell.org/package/base-compat
base-compat>.

See the README for what instances are covered: https://github.com/haskell-compat/base-orphans#readme. See also the what is not covered section.
