Add missing changelog entries for current state of #9586

2014-09-20T21:59:49+00:00

Generalise (some of) Data.List to Foldables (re #9568)

2014-09-20T21:52:57+00:00

This replaces the entities in Data.List conflicting with Data.Foldable
with re-exports of the generalised version from Data.Foldable.

As of this commit, the following compiles w/o error

    module XPrelude (module X) where

    import Control.Monad as X
    import Data.Foldable as X
    import Data.List as X
    import Prelude as X

Turn a few existing folds into `Foldable`-methods (#9621)

2014-09-20T21:47:44+00:00

Turn `toList`, `elem`, `sum`, `product`, `maximum`, and `minimum` into
`Foldable` methods. This helps avoiding regressions (and semantic
differences) while implementing #9586

Set up framework for generalising Data.List to Foldables

2014-09-20T21:38:30+00:00

This renames the Data.List module to Data.OldList, and puts a new
Data.List module into its place re-exporting all list functions.

The plan is to leave the monomorphic versions of the list functions in
Data.OldList to help smooth the transition.

The new Data.List module then will simply re-export entities from
Data.OldList and Data.Foldable.

This refactoring has been placed in a separate commit to be able to
better isolate any regressions caused by the actual list function
generalisations when implementing #9586

This also updates the haskell2010, haskell98, and array submodules

Fix potential `mingw32_HOST_OS` breakage from eae19112462fe77

Define fixity for `Data.Foldable.{elem,notElem}`

2014-09-19T15:54:43+00:00

This was probably just an oversight. With this change the fixity matches
that from `Data.List.{elem,notElem`}`.

Addresses #9610

Auto-derive a few manually coded Show instances

2014-09-19T09:36:55+00:00

In `base`, the instances

  instance Show ()
  instance Show Bool
  instance Show Ordering
  instance Show a => Show (Maybe a)

where defined manually, even though we can leverage GHC's auto-deriver
which is perfectly capable by standalone derivation to avoid boiler-plate
code such as this.
