Re: [Haskell-cafe] Type classes for converting to Text and String

When writing library code that should work with both String and Text I find my self repeatedly introducing classes like:

   class ToString a where      toString :: a -> String

   class ToText a where      toText :: a -> Text

Text is already an instance of IsString which provides IsString. I've defined ToString in my own projects though, it would be nice for it to be defined somewhere (Data.String maybe?).
