[GHC] #11210: Missing instances for Identity and Const

They can all be derived with {{{GeneralizedNewtypeDeriving}}}. It would be useful for me if they were defined in {{{base}}}. These should probably also go into {{{base-orphans}}} and {{{transformers}}} (for versions of {{{base}}} before {{{Identity}}} was moved there). {{{#!hs instance Bounded a => Bounded (Const a b) instance Enum a => Bounded (Const a b) instance Ix a => Bounded (Const a b) instance Semigroup a => Semigroup (Const a b) instance Bounded a => Bounded (Identity a) instance Enum a => Bounded (Identity a) instance Ix a => Bounded (Identity a) instance Semigroup a => Semigroup (Identity a) }}} -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11210 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
