Comment (by guest):

 The point of ExtendedDefaultRules is to get away from the draconian
 Haskell-98 rules.
 The one that is especially annoying is that all classes have to be
 standard ones (that rules should be removed for Haskell', I think).

 I'm not sure why the rules insist on only the form (C v).  If there's some
 technical reason for this I guess I'm out of luck.
