Re: RE: Proposal: Generalize the RandomGen and Random classes

If the random library is changed to use the language extensions MultiParamTypeClasses and FunctionalDependencies, then it will be removed from the Haskell 2011 standard libraries, since there is no proposal for Haskell 2011 to adopt either of those extensions.
