There are lots of high quality libraries, but no major effort to replace the Prelude's privileged position in the language. So it it kind of a minefield to find the correct module/function for your needs. Haskell Platform is a great standard set of imports, but it is only for the commonest libs, beyond that you have again the problem of sorting out excellent libs from some student's throwaway homework project with the same name.
