3544	Add instance IsString ShowS where fromString = showString	basvandijk		"It would be really nice to use [http://www.haskell.org/ghc/docs/latest/html/users_guide/type-class-extensions.html#overloaded-strings OverloadedStrings] when writing a definition of [http://haskell.org/ghc/docs/latest/html/libraries/base/Prelude.html#v:showsPrec showsPrec] in an instance for Show.

The attached patch adds the necessary instance to {{{base/GHC/Show.lhs}}}:

{{{ 
instance IsString ShowS where
    fromString = showString
}}}  

Note that this does require {{{TypeSynonymInstances}}}."	proposal	closed	normal		libraries/base	6.10.4	wontfix			Unknown/Multiple	Unknown/Multiple
