Re: no non-typevariable in instance declarations

does not provide type-system extensions to Haskell'98. Not exactly. NHC98 provides at least the following extension to Haskell 98: * existentialy quantified type variables (By the way, is there any plans to implement multiparameter type classes and instance overlapping in NHC98?) Tha
