@hackage special-functors1.0.0.1

Control.Applicative, Data.Foldable, Data.Traversable (compatibility package)

These are the modules for applicative functors and friends, as found in GHC-6.6 and higher. We provide them for use in versions up to GHC-6.4. This package can be used for backward compatibility.

ToDo:

Add various instances of Foldable and Traversable for base types like Map, but these will be less efficient as you don't have access to their implementations.
