Still I think, such a program looks more natural when it uses recursive modules rather than adding extra arguments to functions. Also this is not only for functions. Instances often use each other in a recursive way: module A where ... instance Foo1 Data1 where ... module B where ... instance Foo2 Data2 where ... module C where ... instance Foo3 Data3 where ... ----------------- Serge Mechveliani [EMAIL PROTECTED] _______________________________________________ Glasgow-haskell-users mailing list [email protected] http://www.haskell.org/mailman/listinfo/glasgow-haskell-users
