Maintainer's Corner

For package maintainers and hackage trustees


Readme for special-functors-

[back to package description]
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.


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.
