Note, the haskell98 and haskell2010 packages would be unaffected by this proposal as it stands.

The (repeatedly raised in this thread) Applicative as a superclass of Monad situation on the other hand, sadly does impact them.

In the special case of adding Traversable and Foldable to Prelude, it worries me that it is about changing Prelude. I am more relaxed about changes to 'base'. However, since Prelude is part of the Haskell 98 and Haskell 2010 specification, I thought that changing Prelude could also be decided by the Haskell Prime committee.
