-- | Converting string-like types to Strings.
--   
--   This library provides the class:
--   
--   class ToString s where toString :: s -> String
--   
--   Instances for String, Char and ShowS are provided. For other instances
--   see the package:
--   
--   <a>http://hackage.haskell.org/package/to-string-instances</a>
--   
--   Also included is a general coercion function between string-like
--   types:
--   
--   fromToString :: (IsString s2, ToString s1) =&gt; s1 -&gt; s2
--   
--   fromToString = fromString . toString
