You can use signum without having Eq, and you can sometimes define signum without having Eq (e.g. on functions). Sometimes you do require (==) to define signum, but it has nothing to do with superclasses. -- __("< Marcin Kowalczyk * [EMAIL PROTECTED] http://qrczak.ids.net.pl/ \__/ ^^ SYGNATURA ZASTÊPCZA QRCZAK _______________________________________________ Haskell-Cafe mailing list [EMAIL PROTECTED] http://www.haskell.org/mailman/listinfo/haskell-cafe
