Oh, there are /lots/ of suggestions. Perhaps too many. But this is one area that could really be improved by the use of ATs or MPTCs with fundeps, and that's stalled some of the concrete proposals, as what exactly is happening for Haskell' isn't too clear. -- Aaron Denney -><- _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
