Conor McBride and I would like to propose some new classes for traversals of containers, based around applicative functors (the abstraction formerly known as idioms):
http://www.soi.city.ac.uk/~ross/traversals/
They are proposed for the base package, and would replace FunctorM.
Comments most welcome.
On line 83-84 or Traversable.hs: -- | Any 'Traversable' can also be made an instance of 'Functor' by -- thng 'fmap' as this function. Maybe thng should be assigning? I'm not sure which word should be there. -- Shae Matijs Erisson - http://www.ScannedInAvian.com/ - Sockmonster once said: You could switch out the unicycles for badgers, and the game would be the same.
