[Haskell-cafe] Language.Haskell and strings

Hi, I'm using Language.Haskell.* and would like to know if it's possible to pretty-print big strings like this: "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa" into something like this: "aaaaaaaa\ \aaaaaaaa\ \aaaaaaaa\ \aaaaaaaa\ \aaaaaaaa\ \aaaaaaaa\ \aaaaaaaa" to respect the limit on number of columns. Can you help me? Is it possible to do that? Thanks, Maurício
