[Haskell-cafe] Re: advantages of using fix to define rcursive functions

I read about the usage of "fix" to define recursive functions. Although I think that I understood how to use "fix", I still wonder what the advantages of "fix" are (as compared to the "conventional" approach to define recursive functions).
