Hello *,
I noticed the following module (trimmed for brevitiy) hiding in `base`:
-- This module deliberately declares orphan instances:
{-# OPTIONS_GHC -fno-warn-orphans #-}
-- | Optional instance of 'Text.Show.Show' for functions:
--
-- > instance Show (a -> b) where
-- > showsPrec _ _ = showString \"\\"
--
-----------------------------------------------------------------------------
module Text.Show.Functions () where
instance Show (a -> b) where
showsPrec _ _ = showString "<function>"
However, I consider this a questionable module to be in `base` due to
its deliberate use of orphan instances. Should this module be
deprecated, removed, alternatively, should the `Show` instance be made a
non-orphan (e.g. by importing it by the `Prelude` module), or shall this
curiousity be just left untouched in `base` in its current form?
Cheers,
hvr
